Historian Michal Kšiňan explains the history behind the Cleveland agreement, the first document on the joint action of the Czechs and Slovaks in the struggle for national liberation in and after WWI. The first Czechoslovak republic was established in 1918 also thanks to Czechs and Slovaks living in the USA. Many of their descendants travel to Slovakia to seek their roots. In 2023, Zuzana Botikova met with Viera Marecová who helps finding Americans tracing their roots.
