Maciej Borkowic (Maćko Borkowic)

Maciej, called Maćko, Borkowic (1298–1360) was voivode of Poznań from 1343 and a leader of Greater Poland's nobility. He campaigned in Red Ruthenia in 1340, and when Casimir III restored the general governorship in 1352 under Wierzbięta z Paniewic, Borkowic led the knightly confederation against the king; Greater Poland descended into civil war.

After killing the voivode of Kalisz he was exiled to Silesia, returned in 1356 and swore fealty at Sieradz in 1358. Arrested in 1360 and tried by the king, he was starved to death in Olsztyn castle tower.
