The paper presents the conclusions of Czech historiography about the beginnings of Czechoslovak-Polish relations in 1918. Czechoslovakia was becoming a new state at that time and its territories had earlier formed a part of the Austro-Hungarian monarchy. In October 1918 the process of creating local organs of a new state began. It also took place in Silesia, where Polish and Czech communities were living together. The Polish community also created its local organs. There were even some contacts established between Polish and Czech local institutions and a provisional territorial agreement was signed. It was not approved by the Prague government, which in November and December 1918 was not able to decide about the future of Silesia. These decisions were taken later.
