Sieciech

Though the exact dates of his birth and death are unknown, he is said by Gallus Anonymus to have lived in the second half of the 11th century.

[citation needed] His alleged despotic conduct resulted in a number of nobles (especially those from Silesia) being forced to leave the country.

The disgruntled nobles sought to limit his influence by proposing that the country should be divided between Władysław I Herman and his sons Zbigniew and Boleslaw III Wrymouth.

[citation needed] Their wishes were granted when in 1100 Sieciech was stripped of his land and titles by Wladyslaw I Herman and banished from the country.

[1][2][3] The town of Sieciechów (Castrum Sethei), judging by Gallus, was named after Sieciech (Setheus).
