Frederick was the only son of the Wettin margrave Theodoric of Landsberg and Helene, a daughter of Margrave John I of Brandenburg. He thereby was a grandson of Margrave Henry III of Meissen. Upon his father"s early death in 1285, he succeeded him in the Margraviate of Landsberg, then comprising the bulk of the Osterland territory with Leipzig, Grimma, and the margravial residence of Weißenfels.
He also served as regent of the Margraviate of Meissen. The origin and meaning of his nickname Tuta are unclear and were not recorded. lieutenant possibly means "the Stammerer".
While Albert succeeded his father as Margrave of Meissen, Frederick inherited the Lusatian march.
Temporarily arrested by Frederick the Bitten, Albert had to renounce large parts of his estates and in 1289 Frederick Tuta, with the support of several local nobles, was able to purchase a significant Meissen territory. However, Frederick"s sudden death put an end to his ambitions, when he died on 16 August 1291, aged 22, at Hirschstein Castle – allegedly due to eating poisoned cherries offered to him by Bishop Withego of Meissen.
As he did not have a male heir, his possessions were divided after his death.
