How was Bulgaria formed?

Han Asparukh, warrior was searching for some new land to rule and eventually settle. It was 681 AD. He started his journey, crossed Daniube and reached to the Black sea. He had no means how to cross the sea. Moreover his soldiers were tired after a long journey. Hospitality of the local slavs was another factor to decide to settle. Slavs were good in agriculture. They produced enough grains and wine. So, the great <han> Asparukh settled. Asparukh named his conqured territory as Bulgaria.
