Мешко II
Following the baptism, construction began of Poznań's cathedral, the first in Poland. Poznań was probably the main seat of the first missionary bishop sent to Poland, Bishop Jordan. The Congress of Gniezno in 1000 led to the country's first permanent archbishopric being established in Gniezno (which is generally regarded as Poland's capital in that period), although Poznań continued to have independent bishops of its own. Poznań's cathedral was the place of burial of the early Piast monarch: Mieszko I, Boleslaus I, Mieszko II Lambert, Casimir I, and later of Przemysł I and King Przemysł II.
