Timeline of events, 1919-69

The dates given in this table for the openings of recognised diplomatic missions are the dates when a resident Irish diplomat was first based in the locations concerned. In most cases diplomatic relations had been established many years before resident missions were established and non-resident ministers and ambassadors had been appointed. Particularly from 1946 onwards, ambassadors in the list of missions below were also accredited to other countries and institutions. Prior to 1946 Irish diplomatic missions tended to be either legations or high commissions. Ireland’s first ‘Embassy’ was opened in 1946, when the first ambassador to the Holy See was appointed.  Subsequently high commissions became embassies after Ireland left the Commonwealth in 1949. From the 1950s on legations were regularly upgraded to full embassies.
