Known in ancient times as Saso, the island was occupied by Italy on 30 October 1914, a move ratified on 26 April 1915 by the secret Treaty of London. After World War I, Albania formally ceded the island to Italy, 2 September 1920 as part of the Albano-Italian protocol.
It was restored to Albanian control on 10 February 1947 as a result of the treaties ending World War II.
During most of the Italian occupation, postage stamps of Italy were used. However, in 1923, eight of the current stamps of Italy were overprinted "SASENO". They are not particularly rare, and cost collectors about 8-10 US$ each, although uses on cover are harder to find.Postage stamps
