On the 24th of November, 1995, Ireland became the last country in Europe to legalise divorce. This occurred because of a referendum to change the constitution – not the first attempt to achieve this.

Divorce had been specifically forbidden in the 1937 Irish constitution. A heavily Catholic country, there was very strong opposition to the legal breakup of a marriage, just as there was when it came to the legalisation of contraception, which was only made available in the 1980s.
The success of the 1995 referendum was a close thing; the results were just over 50% in favour and 49.79% opposed.
