Question: has a country won eurovision twice in a row

Answer: Yes, Ireland has finished first seven times, more than any other country, Ireland also won the contest for three consecutive years (1992, 1993, 1994), more consecutive years than any other country. Three countries have won twice in a row, Spain (1968 and 1969), Luxembourg (1972 and 1973) and Israel (1978 and 1979). Along with Switzerland's win in the first contest, Serbia is the only other country to win with its debut entry (in 2007), though Serbia had competed prior as part of Yugoslavia and Serbia and Montenegro. Under the voting system used between 1975 and 2015, the winner of the contest was decided by the final voting nation on eleven occasions.
