...heading out of Turkey: I caught an overnight train from Istanbul to Sofia, Bulgaria. Here is another map for reference (again, pink is current travels, blue is former routes).

My goal was to visit the countries in Eastern Europe that I had not yet seen. First stop: Bulgaria. Not too much to report except a huge snowstorm, barely any English speakers, and terrible customer service at the bus station. My highlight was a young Malaysian (Chinese ethnicity) fellow who I met on the train to Sofia. He was stationed in Sofia for a while for his tech job. He invited me to stay with him and his Chinese roommates in their apartment on the outskirts of Sofia. This made for a relaxing night while the snow fell.
Next stop: the former Yugoslav republics. Here is a map of Eastern Europe in the early 80s, well before the Soviet Union, Yugoslavia and Checkoslovakia all broke apart
...and here is my attempt at history (warning, my version is likely incorrect in some fashion).
Yugoslavia (translation: "south slavs") was made up of many ethnic groups. At the core were the Serbs. After the Soviet Union collapsed, parts of Yugoslavia started peeling away. Each ethnic group wanted their own nation. First was Slovenia...this country has now become one of the most successful stories of Eastern Europe. It is a tiny nation that has a great tourism industry--which Strom and I visited in 2000. (it is blue below). Compared to the independence of the other parts of Yugoslavia, Slovenia escaped with very little bloodshed.
Second to peel away was Croatia. However, the geography of the ethnic groups was not clear cut. This resulted in Serbia (the core of former Yugoslavia) attacking Croatia as it tried to achieve independence. War ensued. Now Croatia has a quickly developing economy and a great tourism industry centered on the fact that most of the country hugs the scenic Adriatic coast.
You may not be able to read the text on this map, but the different colors are different ethnic groups in the region. Compare the colors to the dark lines, which represent the current national boundaries. The basis of much of the conflict in this region is people's attempt to have an independent country for their own ethnic group. This generally means capture as much land as you can, and then kick out or kill anyone who does not belong.

As you can tell from the above map, this has resulted in some parts where ethnicity corresponds to national borders, and other parts where it does not. One irony of all this fighting is that some of these ethnic groups are actually from the same "stock." Some can not be told apart until they speak.
The third country to break away from Serbia (the remaining core of Yugoslavia) was Bosnia, with significant bloodshed. As the map above shows, many ethnic groups still exist within Bosnia and Hercegovina. This is a result of the peace deal brokered by Clinton...
Macedonia (in yellow above) also managed to achieve independence, leaving behind the regions of Serbia, Montenegro and Kosovo. These 3 regions were a country called "Serbia and Montenegro" until Montenegro became independent a couple years ago...leaving Serbia (still containing the region of Kosovo).
From Bulgaria I caught a bus to Skopje, the capital of Macedonia. Macedonia may conjure up images of Greece. This is because Macedonia is a region that is mostly in northern Greece...but also partially where the country of Macedonia now is. This region that broke away from Serbia needed a name, but Greece did not want the name Macedonia used. So the small country was officially named FYROM (the Former Yugoslav Republic of Macedonia). For all purposes, most people just call the country Macedonia now.
I noticed a couple things in Macedonia. First, I noticed that the capital Skopje is perhaps one of the only places in the world that has pj in the middle of the name. Second, I noticed this statue below (women and children better grab their arms too!). Next, I found a restaurant serving vegan Balkan food. That was a rarity...I ate quite a bit there. Finally, I noticed that I could take a bus north to Kosovo.
In the below map, Kosovo is part of the brown ethnic group, i.e. the Albanians. However, it is still part of the country now called Serbia. So the Serbians have tried to cleanse their country of the Albanian people (i.e. remove them from Kosovo where they live)...and the Albanians have fought back. This conflict happens to be along religious lines as well (the Albanian people are Muslim and the Serbians are Orthodox Christian), but religion is not the problem per se...ethnicity is the problem. A fragile peace currently exists in Kosovo only because of UN and US peacekeepers.
