The Irish Deaf Society says that ISL "arose from within deaf communities", "was developed by deaf people themselves" and "has been in existence for hundreds of years". According to Ethnologue, the language has influence from both LSF and BSL, as well as from signed French and signed English, BSL having been introduced in Dublin in 1816. The first school for deaf children in Ireland was established in 1816 by Dr. Charles Orpen. The Claremont Institute was a Protestant institution and given that Ireland was a part of the United Kingdom, it is no surprise that BSL was used for teaching and learning. McDonnell reports that the Irish institutions - Catholic and Protestant - did not teach the children to speak and it was not until 1887 that Claremont report changing from a manual to an oral approach. For the Catholic schools, the shift to oralism came later: St. Mary's School for Deaf Girls moved to an oral approach in 1946 and St. Joseph's School for Deaf Boys shifted to oralism in 1956, though this did not become formal state policy until 1972. Sign language use was seriously suppressed and religion was used to further stigmatise the language. The fact that the Catholic schools are segregated on the basis of gender led to the development of a gendered-generational variant of Irish Sign Language that is still evident today. ISL was brought by Catholic missionaries to Australia, and to Scotland and England, with remnants of ISL still visible in some variants of BSL, especially in Glasgow, and with some elderly Auslan Catholics still using ISL today. In South Africa, the Dominican nuns who established Catholic Schools saw a need for a school for the deaf, but due to resource constraints were not in a position to do this immediately. Instead, they wrote back to their Mother House in Cabra requesting an experienced teacher of the deaf. A deaf teacher, Ms. Bridget Lynne, responded. Remnants of gendered generational Irish Sign Language are thought to still be visible in some dialects of South African Sign Language, which can probably be traced back to Ms. Lynne.
The "Recognition of Irish Sign Language for the Deaf Community Bill 2016" passed all stages in the Oireachtas on 14 December 2017, and was signed into law under the revised title, The Irish Sign Language Act 2017. The Act was signed into law by the President of IrelandMichael D Higgins on 24 December 2017. The Act, due to commence formally in December 2020, requires that public services are available through ISL and also outlines the need for greater access to education through sign language. Prior to the passage, there was no automatic right for deaf people to have an ISL interpreter. For the deaf community, recognition of ISL means more legal rights and better access to public services - including education, healthcare, media and banking.
