Having deserted the Ottoman army, Skanderbeg (pictured) arrived in the Albanian city of Krujë and, using a forged letter from Sultan Murad II to the governor of Krujë, became lord of the city.

The Ottoman Empire, also called the Turkish Empire, was an imperial realm that controlled much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe, between the early 16th and early 18th centuries.

Gjergj Kastrioti, commonly known as Skanderbeg, was an Albanian warlord and military commander who led a rebellion against the Ottoman Empire in Southeast Europe.

Krujë is a town and a municipality in north-central Albania. Located between Mount Krujë and the Ishëm River, the city is 20 km north of the capital of Albania, Tirana.

Murad II was twice the sultan of the Ottoman Empire, from 1421 to 1444 and from 1446 to 1451.
