Rebellion of the Seimeni and Dorobanți

The rebellion of the Seimeni and Dorobanți or Hrizea's revolts broke out on 26–27 February 1655, in Wallachia.

The timing of the events is controversial, but the reason is Constantin Șerban's desire to deprive himself of the services of the seimeni, which Matthew Basarab relied on completely. At the beginning of the uprising, between 14 and 32 boyars were killed.

It is an uprising of both "Praetorian" and ethnic origin. It is headed by Hrizea of Bogdănei - a swordsman and a foster parent. Hrizea was a bed-keeper, locksmith, and worshipper, like his mother-in-law, who was called Dragutin or Dragomir - under Matthew Basarab.

The uprising was extinguished after the Battle of Hopleja on 26 June 1655.
