Amazing Amazonia (Part 1)

Amazonia or the Amazon Jungle, is a moist broadleaf forest that covers most of the Amazon basin of South America. This basin encompasses 2,700,000 square miles, 2,100,000 square miles of which are covered by the rainforest.

This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in six other nations.

The Amazon represents over half of the planet's remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species.

Sahara Desert dust 

More than 56% of the dust fertilizing the Amazon rainforest comes from the Sahara desert. The dust contains phosphorus, important for plant growth. The yearly Sahara dust replaces the equivalent amount of phosphorus washed away yearly in Amazon soil from rains and floods. Up to 50 million tons of Sahara dust per year are blown across the Atlantic Ocean.

Deforestation of the Amazon rainforest

The cattle business has been responsible for about 80% of all deforestation in the region, or about 14% of the world's total annual deforestation, making it the world's largest single driver of deforestation.

The annual rate of deforestation in the Amazon region dramatically increased from 1991 to 2003. In the nine years from 1991 to 2000, the total area of Amazon rainforest cleared since 1970 was comparable to the land area of Spain, Madagascar or Manitoba. Most of this lost forest was replaced by pasture for cattle.

Visual Quick Study - Fracking in New York State

Much of western New York sits atop the natural gas-rich Marcellus shale, the same formation that has made neighboring Pennsylvania one of the country’s largest natural gas producers because of high-volume hydraulic fracturing operations. The Marcellus shale, stretching from Tennessee to New York, is estimated to contain about 84 trillion cubic feet of recoverable shale gas, up to 9 trillion of which is in the Empire State.

Did You Know?
December 22nd, 2014 - New York State became the first energy-rich state to ban the method of high-volume hydraulic fracturing, or fracking, used to extract natural gas found in underground shale formations. The ban came at about the same time that the Canadian provinces of Quebec and New Brunswick officials said they’d prevent shale gas development, too.

The Yugoslavian Mess

I recently took this book out of the library and the details of the Balkan genocides during World War Two absolutely shocked me into posting this.

The infamous Nazi concentration camps, the Holocaust and Stalin’s Gulags are well-known tragic gruesome facts of history but the brutality of the Croatian Ustaše and other mass murders in the Balkans during World War Two are sadly not as publicized.

Deep Divisions

Historically, Yugoslav lands have been located in the "fracture zone" between East and West. Christianity vs. Islam, Catholic vs. Orthodox -- the rivalries and tensions ran deep.


Following centuries in which the territories had been divided between the Ottoman Empire and Austria-Hungary, Yugoslavia came into existence after World War I under the name of the Kingdom of Serbs, Croats and Slovenes in 1918. It was renamed the Kingdom of Yugoslavia in 1929 and was invaded by the Axis powers in 1941.

After World War II, in 1946, Yugoslavia was renamed the Federal People's Republic of Yugoslavia when a communist government was established. After Tito's death in 1980, ethnic tensions grew in Yugoslavia.

In the 1990s, the country disintegrated into full scale internal war which culminated in the Siege of Sarajevo and the tragic Srebrenica massacre. From 1992 to 1996, Sarajevo suffered the longest siege of a city in the history of modern warfare (1,425 days long) during the Bosnian War. The Srebrenica massacre was the genocidal killing, in July 1995, of more than 8,000 Muslim Bosniaks, mainly men and boys, in and around the town of Srebrenica during the Bosnian War.

This post will focus primarily on the period during World War Two when the region was divvied up between Axis powers and the mind-boggling huge volume of mass murders and ethnic cleansing that took place.

World War Two

In 1941, the territory of Yugoslavia was swiftly conquered by Axis forces and partitioned between Germany, Italy, Hungary, Bulgaria and client regimes. From this point on it gets complicated. Not only were the "locals" involved in fighting their occupiers, simultaneously they were involved in fighting each other...


After the partition of the region by the Axis powers, a guerrilla liberation war was fought against the Axis occupying forces and their locally established puppet regimes, including the Independent State of Croatia and the Government of National Salvation in Serbia, by the Communist-led republican Yugoslav Partisans.

Simultaneously, a multi-side civil war was waged between the Partisans, the Serbian royalist Chetniks, Croatian nationalist Ustaše and Home Guard, as well as Slovene Home Guard troops.

Mass Murder and Genocide

The human cost of the war was enormous. The number of war victims is still in dispute, but is generally agreed to have been at least one million. Non-combat victims included the majority of the country's Jewish population, many of whom perished in concentration and extermination camps.

  • The Croatian Ustaše regime committed genocide against local Serbs, Jews, and Roma. 
  • The Chetniks pursued ethnic cleansing against Muslims and Croats 
  • The Italian occupation authorities pursued against Slovenes. 
  • Partisans carried terror and executions against families of Chetnik fighters and "Class enemies".
  • German troops carried out mass executions of civilians in retaliation for resistance activity 

Croatia and the Ustaše

The United States Holocaust Memorial Museum has estimated that Ustaša authorities murdered between 320,000 and 340,000 ethnic Serb residents of Croatia and Bosnia between 1941 and 1945 (the period of Ustaše rule), of whom between 45,000 and 52,000 were murdered at the Jasenovac concentration camp alone.

The scale of the atrocities shocked even German and Italian occupying forces. The Ustaše considered any "undesirables" were subject to mass murder.  The strategy to achieve their goal was:
  • One third of the Serbs were to be killed
  • One third of the Serbs were to be expelled
  • One third of the Serbs were to be forcibly converted to Catholicism

The Jasenovac Concentration camps
These mass-executions took place at various locations. At the "Granik" camp, internees were hung by a crane, had their intestines and necks slashed, then were thrown into the river after being hit by blunt tools in the head. Later, inmates were tied in pairs, slashed in the stomach and thrown into the river while still alive.

At a ceremony on October 9th, 1942, Vjekoslav "Maks" Luburić, the commander-in-chief of all the Croatian camps, announced the great "efficiency" of the Jasenovac camp. During the banquet which followed, he bragged: "We have slaughtered here at Jasenovac more people than the Ottoman Empire was able to do during its occupation of Europe.”

The exact number of victims is not known but by the end of WWII, it is estimated the Ustaše, exterminated 30,000 Jews, about 29,000 Gypsies, and between 300,000 and 600,000 Serbs.

Serbian Aspirations

Greater Serbia is the ideology to unite all Serbs (or all territory historically ruled or populated by Serbs) into one state, claiming, depending on the version, different areas of many surrounding countries. Greater Serbia would incorporate all regions of traditional significance to Serbs, including regions outside Serbia that are populated by Serbs.

During the World War II Axis occupation, the Serbs were divided into two factions, (1) the resistance was mainly made by the Chetniks, who defended the restoration of the Monarchy, and (2) the Partisans, who supported the creation of a communist Yugoslav state.

During the World War II, the Serbian royalist Yugoslav Army attempted to define its vision of a postwar future creating an even larger “Homogenous Greater Serbia”, incorporating not only Bosnia and much of Croatia but also chunks of Romania, Bulgaria, Albania and Hungary in areas where Serbs don't represent a significant minority.
In the territories under their military control, Chetniks applied a policy of ethnic cleansing and terror tactics against ethnic Croats and Bosniaks. These terror tactics took various forms, including killing of the civilian population, burning of villages, assassinations and destruction of property. The terror tactics used by the Chetniks against the Croats were a reaction to the terror carried out by the Ustaše, but Croats and Bosniaks living in areas that were intended to be part of Greater Serbia were cleansed of non-Serbs regardless…

Throughout the war, the Chetnik movement remained mostly inactive against the occupation forces, and increasingly collaborated with the Axis, eventually losing its international recognition as the Yugoslav resistance force. After the fall of Belgrade to Soviet and Partisan troops in 1944, there was little hope of the Chetniks surviving as a legitimate fighting force in Yugoslavia and in 1945, the victorious Partisans took possession of the country's territory.

Bleiburg Repatriations
The Bleiburg repatriations were a series of events that took place after the end of World War II, when tens of thousands of soldiers and civilians associated with the Axis fleeing Yugoslavia were repatriated to that country. Thousands were murdered or subjected to forced labor camps.

The modern-day consensus is that the number of deaths of the forced marches and in death camps rose to tens of thousands, and included civilians. The exact number of those who met their death in Bleiburg is impossible to ascertain accurately. The number of victims has been inflated by pro-Ustaša sources for propaganda purposes, while communist sources have been diminishing it for similar reasons.

The remainder of the Ustaše, and their supporters in the Croatian diaspora, used Bleiburg as their central myth and used as a tool for historical revisionism  The number of victims were artificially inflated...
David Bruce MacDonald wrote:
“Inflating the numbers of dead at Bleiburg had several layers of significance. Firstly, it gave the Croats their own massacre at the hands of Serbs and/or Communists, which allowed them to counter the Serbs' Jasenovac genocide with one of their own”

Hatred and Resentment

A seemingly impossible hodgepodge of various ethnic groups make up the Yugoslavia region.



The deep-rooted distrust between these various ethnic groups and its history of violence and genocide inevitably led to the conflicts and continued mass murders that took place in the 1990s.

Mongol Conquests

After reading this interesting book on the Empire of the Mongols, it behoved me to post maps and some of the pros and cons of this remarkable period in history.

Mongol Conquests

Historians regard the Mongol raids and invasions as some of the deadliest conflicts in human history up through that period. Some Hungarian historians claim that Hungary's long resistance against the Mongols actually saved Western Europe.

Under the leadership of Genghis Khan and his descendants in the 13th century, the Mongols quickly built an empire that stretched from Korea to eastern Europe - the largest continuous area of land ever controlled by one ruling family. The rise of the Mongols marked the last major clash between nomadic and sedentary cultures. 


Animated!

Barbaric, Mass-Murdering Hordes...

Ancient sources described Genghis Khan's conquests as wholesale destruction on an unprecedented scale in certain geographical regions, causing great demographic changes in Asia.

  • The total population of Persia may have dropped from 2,500,000 to 250,000 as a result of mass extermination and famine.
  • China reportedly suffered a drastic decline in population during the 13th and 14th centuries. Before the Mongol invasion, Chinese dynasties reportedly had approximately 120 million inhabitants; after the conquest was completed in 1279, the 1300 census reported roughly 60 million people.
  • About half the population of Kievan Rus' may have died during the Mongol invasion of Rus.;
  • Historians estimate that up to half of Hungary's population of two million were victims of the Mongol invasion of Europe.

...Or Enlightened Despots?

The Mongol army led by Genghis Khan subjugated more lands and people in twenty-five years than the Romans did in four hundred. In nearly every country the Mongols conquered, they brought an unprecedented rise in cultural communication, expanded trade, and a blossoming of civilization.

They united Eurasia in a truly international trading system, encouraged new forms of communication, and demonstrated the value of religious tolerance at a time when religious differences often led to wars.

Visual Quick Study: Kurdistan


Kurdistan

Kurdistan roughly encompasses the northwestern Zagros and the eastern Taurus mountain ranges.




Kingdom of Corduene in 60 B.C


Medieval period

Kurdistan in the Middle Ages was a collection of semi-independent and independent states called "emirates". It was nominally under indirect political or religious influence of Khalifs or Shahs.

In the 16th century, after prolonged wars, Kurdish-inhabited areas were split between the Safavid and Ottoman empires. After the Battle of Chaldiran in 1514 up until the aftermath of World War I, most Kurdish areas were generally under Ottoman rule.

Kurdish Independent Kingdoms and Autonomous Principalities circa 1835.

World War I and the Treaty of Sèvres

After the collapse of the Ottoman Empire, the Allies contrived to split Kurdistan among several countries, including Kurdistan, Armenia and others (as detailed in the ultimately unratified Treaty of Sèvres). However, the reconquest of these areas by the forces of Kemal Atatürk caused the Allies to accept the renegotiated Treaty of Lausanne and the borders of the modern Republic of Turkey, leaving the Kurds without a self-ruled region. Other Kurdish areas were assigned to the new British and French mandated states of Iraq and Syria.

Greek History - The Hellenistic Period (Part Two)

The Empire of Alexander The Great

Alexander the Great became the leader of the Greek kingdom of Macedonia and had built an empire that stretched from Greece all the way to India. That brief empire-building campaign changed the world: It spread Greek ideas and culture from the Eastern Mediterranean to Asia.
The Empire of Alexander The Great

“Hellenistic Period” (323 B.C. until 31 B.C)

Known as the “Hellenistic Period”, it lasted from the death of Alexander in 323 B.C. until 31 B.C., when Roman troops conquered the last of the territories that the Macedonian king had once ruled.

Following Alexander's death in 323 BC. His generals Ptolemy, Antigonus, Parmenion, Cassander, and Seleucus engaged in a bitter struggle to carve out personal kingdoms from Alexander's conquests. After 40 years of war, three major dynasties were settled on.
Alexander's Empire was divided amongst his generals

1 - Ptolemaic Empire

Ptolemy controlled Egypt and created a Ptolemaic dynasty that ruled Egypt until its absorption into the Roman Empire by Augustus in 30 B.C.

2 - Seleucid Empire

Seleucus created in the Near East a large empire, sometimes stretching as far as Iran and even India.

3 - Antigonid Empire

 Finally, in Macedon the Antigonid dynasty ruled the smallest division of Alexander's Empire and had the most troubles from the start. The first founder of the Antigonid Dynasty was Antigonas, who gained control of Asia Minor after Alexander’s death. He attempted to reunite the empire under his own rule and declared himself king, but he was defeated and killed in 301 BC.

After numerous battles with neighboring kingdoms and losses to Seleucus, the Antigonid Dynasty ended up hemorrhaging most of Asia Minor (Anatolia) and was considerably reduced in size.
