Liechtenstein women's suffrage referendum, 1984: A referendum on the introduction of women's suffrage in national elections was held in Liechtenstein on 1 July 1984.  Following the introduction of female suffrage in neighbouring Switzerland at the federal level after a referendum in 1971 (although women had had the right to vote in many cantons and municipalities before this), Liechtenstein had been the only remaining European country to deny women the right to vote.  Referendums had been held in 1968, 1971 and 1973 (the latter two limited to men), but on each occasion voters had rejected its introduction, despite the support of newspapers and both major political parties.  Nevertheless, some municipalities had since introduced female suffrage at a local level, starting with Vaduz in 1976, and women had been elected to the local councils of Vaduz and Gamprin in 1983.

He moved to Toronto in 1929, studied at the TCM with MacMillan (organ) and Willan (theory and composition), and was organist 1931-1938 at the Church of the Messiah and 1938-1966 at Bloor Street United Church, where he led the choir in many large works.  At the TCM he served at first, 1929–1946, as registrar of examinations, and then, 1946–1966, as registrar.  He gave organ recitals in many parts of Canada and on the CBC and was president 1945-1947 of the CCO.  He was also assistant conductor and coach 1942-1957, and conductor 1957-1960, of the Toronto Mendelssohn Choir.  Of his work with the choir, George Kidd wrote, 'The overall effect is one of good discipline, a clear understanding, and a sincerity that spreads itself over all sections'.  Silvester wrote a number of short choral works (published by Harris) and songs (published by Western).  His Chorale "Prelude on Rockingham" has been recorded by Eric Robertson.

Cantonal rebellion: The Cantonal rebellion was a cantonalist uprising that took place during the First Spanish Republic, starting on July 12 of 1873 in Cartagena.  In the following days it spread through many regions including, Valencia, Andalusia (especially Granada), Cartagena (which endured for several months the besieging army of Nicolás Salmerón) and in the provinces of Salamanca and Ávila, all of them in places that came to articulate cantonalism.  It can also be noted, the attempt to establish cantons took place in Extremadura, Coria, Hervás and Plasencia.  Pi y Margall, seeing that cantons declared independent by the tardiness of the taxation of improvements, resigned from his post to be succeeded by Salmerón.
