The Social Democratic Party of the Danube (SDP) was a short-lived political party in the Danubian Federation, established in 1860. The group was the first Socialist party in the Danubian Federation, formed from elements within the Radical Union of the Federation (RUF).
The establishment of the Social Democratic Party is often traced to Prague, following the 1860 Presidential elections. During the election, radicals had secured a unexpected victory - scoring an impressive public vote following a weak Conservative showing. The radical nucleus, in Prague, was enguled by Radical thought and sentiment.
