From the late 1980s, allegations of sexual abuse of children associated with Catholic institutions and clerics in several countries started to be the subject of sporadic, isolated reports. In Ireland, beginning in the 1990s, a series of criminal cases and Irish government enquiries established that hundreds of priests had abused thousands of children over decades. Six reports by the former National Board for Safeguarding Children in the Catholic Church established that six Irish priests had been convicted between 1975 and 2011. This has contributed to the secularisation of Ireland and to the decline in influence of the Catholic Church. Ireland held referenda to legalise same-sex marriage in 2015 and abortion rights in 2018.
