Czech Republic–Slovakia relations
Before 1918, both countries were part of Austria–Hungary. However, after the Ausgleich of 1867 Czechia belonged to the Austrian Empire while Slovakia belonged to the administratively separate Kingdom of Hungary, and between 1918 and December 31, 1992, both countries were part of Czechoslovakia. 
Both countries established diplomatic relations on January 1, 1993. These international relations are usually referred to or described as "very good", "cordial", and "above standard" in the media. When a Czech or Slovak president is inaugurated, very often his first international visit is to the former part of the common country. The same custom applies to newly elected prime ministers of the Czech Republic and Slovakia.
Václav Havel
Despite increasing political tensions between the Czechs and the Slovaks in 1992, Havel supported the retention of the Czech and Slovak Federative Republic prior to the dissolution of the country. Havel sought re-election in 1992. Although no other candidate filed, when the vote came on 3 July, he failed to get a majority due to a lack of support from Slovak deputies. The largest Czech political party, the Civic Democratic Party, let it be known that it would not support any other candidate. After the Slovaks issued their Declaration of Independence, he resigned as President on 20 July, saying that he would not preside over the country's breakup.
