Ioniță Caloian
Kaloyan of Bulgaria annexed several important cities, while the Angeloi squandered the public treasure on palaces and gardens and attempted to deal with the crisis through diplomatic means. Byzantine authority was severely weakened, and the growing power vacuum at the centre of the empire encouraged fragmentation, as the provinces began to look to local strongmen rather than the government in Constantinople for protection. This further reduced the resources available to the empire and its military system, as large regions passed outside central control.
