Sypniewskis also had estates in Polesie, formerly the largest province of Poland (currently part of Belarus and Ukraine), several near the city of Żytomierz (currently under Ukrainian jurisdiction since 1945) and large manorial estate crowned with beautiful palace until the end of the 18th century near the city of Homel (currently under Belarussian jurisdiction since 1945); only portion of the cellars and some of the foundations in the ground is what remains today from this once wealthy estate, which used to provide living for about 500 peasant families. Politician Jan Odrowaz-Sypniewski was born there around 1760. He was a legate of the Polish–Lithuanian Commonwealth's Great Parliament and one of the promoters of the first in Europe democratic Constitution of May 3, 1791 (and second in the world, after the United States Constitution). His grandson, Dyonizy Odrowaz-Sypniewski, an architect, exiled to United States and U.K., where he published – at his own expenses – many treatises and political books regarding Partitions of Poland and advocated for restitution of Poland in general. His avid anti-Russian, anti-Prussian and anti-Austrian activities didn't go well with U.K. government (all 3 countries being allies of British Empire at the time). Once he became persona non grata in Britain and was forced to leave the country, he settled in Brasil, where he built roads and bridges.
