The Balkan range runs 560 km from the Vrashka Chuka Peak on the border between Bulgaria and Serbia eastward through central Bulgaria to Cape Emine on the Black Sea. The highest peaks of the Balkan Mountains are in central Bulgaria. The highest peak is Botev at 2,376 m, which makes the mountain range the third highest in the country, after Rila and Pirin. The mountains are the source of the name of the Balkan Peninsula.
The mountain range forms the watershed between the Black Sea and Aegean Sea catchment areas, with the exception of an area in west, where it is crossed by the spectacular Iskar Gorge. The karst relief determines the large number of caves, including Magura, featuring the most important and extended European post-Palaeolithic cave painting, Ledenika, Saeva dupka, Bacho Kiro, etc. The most notable rock formation are the Belogradchik Rocks in the west.
There are several important protected areas: Central Balkan National Park, Vrachanski Balkan Nature Park, Bulgarka Nature Park and Sinite Kamani Nature Park, as well as a number of nature reserves. The Balkan Mountains are remarkable for their flora and fauna. Edelweiss grows there in the region of Kozyata stena. Some of the most striking landscapes are included in the Central Balkan National Park with steep cliffs, the highest waterfalls in the Balkan Peninsula and lush vegetation. There are a number of important nature reserves such as Chuprene, Kozyata stena and others. Most of Europe's large mammals inhabit the area including the brown bear, wolf, boar, chamois and deer.
The Balkan Mountains played an enormous role in the history of Bulgaria since its foundation in 681 AD, and in the development of the Bulgarian nation and people.

<em>The Peloponnesian War was an ancient Greek war fought by the Delian League led by Athens against the Peloponnesian League led by Sparta. Historians have traditionally divided the war into three phases. In the first phase, the Archidamian War, Sparta launched repeated invasions of Attica, while Athens took advantage of its naval supremacy to raid the coast of the Peloponnese and attempt to suppress signs of unrest in its empire. This period of the war was concluded in 421 BC, with the signing of the Peace of Nicias. That treaty, however, was soon undermined by renewed fighting in the Peloponnese. In 415 BC, Athens dispatched a massive expeditionary force to attack Syracuse, Sicily; the attack failed disastrously, with the destruction of the entire force in 413 BC. This ushered in the final phase of the war, generally referred to either as the Decelean War, or the Ionian War. In this phase, Sparta, now receiving support from the Achaemenid Empire, supported rebellions in Athens's subject states in the Aegean Sea and Ionia, undermining Athens's empire, and, eventually, depriving the city of naval supremacy. The destruction of Athens's fleet in the Battle of Aegospotami effectively ended the war, and Athens surrendered in the following year. Corinth and Thebes demanded that Athens should be destroyed and all its citizens should be enslaved, but Sparta refused.</em>
