Edin Osmić (born December 22, 1978), better known by his stage name Edo Maajka, is a Bosnian rapper, record producer and songwriter. His popularity brought his group, Disciplinska Komisijaa, which Frenkie is a part of, to the mainstream. His stage name literally means "Edo the Mother". He is currently the most sought after hip hop star in Bosnia and the surrounding countries.

Edin Osmić was born and raised in Brčko (at the time SR Bosnia and Herzegovina, SFR Yugoslavia) where he finished his elementary schooling. In 1992 when the Bosnian war started, he left Bosnia and Herzegovina and went to Zagreb, the capital of Croatia, where he began attending secondary mechanical engineering school. After the war, he returned to Bosnia to study criminal law in Tuzla, but never graduated.

He took an interest in hip-hop when he was still in high school and began battling at the age of 15. He also recorded a few of his demos on his own, creating his own backing by beatboxing. He went to Tuzla and became a member of the hardcore rap group Diskord, later named Odbrana (Defence). The group became one of the best in the city of Tuzla and all of Bosnia. Their demo single "Odbrana '99" (Defence '99) was the hit of the year on the "Radio Hit" station in Brčko.

Edo (江戸, Edo^?, literally "bay-entrance" or "estuary"), also romanized as Yedo or Yeddo, is the former name of the Japanese capital Tokyo. It was seat of power for the Tokugawa shogunate, which ruled Japan from 1603 to 1868. During this period it grew to become one of the largest cities in the world and home to an urban culture centered on the notion of a "floating world".

From the establishment of the Tokugawa bakufu's headquarters at Edo, although Kyoto remained the formal capital of the country the de facto capital was now Edo; it was the center of political power. Edo grew from what had been a small, little-known fishing village in 1457 to a metropolis with an estimated population of 1,000,000 by 1721 (the largest city in the world at the time).

Edo was repeatedly devastated by fires, with the Great Fire of Meireki in 1657 (in which an estimated 100,000 people died) the most disastrous. During the Edo period there were about 100 fires (most begun by accident, often quickly escalating and spreading through neighbourhoods of wooden machiya which were heated with charcoal fires. Between 1600 and 1945, Edo/Tokyo was leveled every 25–50 years or so by fire, earthquakes, tsunami, volcanic eruptions or war.
