John Donnellan was born in Dunmore, County Galway in 1937. He was born into a family that had strong interests in both Gaelic games and Irish politics. His father, Michael Donnellan, had won an All-Ireland Senior Football Championship (SFC) medal with Galway in 1925, later becoming a TD for Clann na Talmhan. John Donnellan would go on to follow in his father's footsteps in both of these pursuits, although for a different party. John's son, Michael, would also go on to play football for Galway, winning All-Ireland SFC medals in 1998 and 2001.[2]
Donnellan played his club football with the Dunmore McHales club in the north of County Galway. He enjoyed much success with the club, beginning in 1961 when he won a senior county championship for the first time. In 1962 Donnellan won a county league medal before claiming a second county championship title in 1963. This last win was later converted into a Connacht club football championship. In 1966 Donnellan's club completed the double of county league and county championship victories. He completed a great run of success by capturing back-to-back county championship and Connacht club titles in 1968 and 1969.
Inter-county
Donnellan's career as an inter-county footballer began in the late 1950s. He won an All-Ireland Junior Football Championship title with the Galway junior team in 1958 and he quickly joined the senior side. Two years later in 1960 Donnellan won his first Connacht title; however, Galway were later defeated in the All-Ireland SFC semi-final. Three years later in 1963 he captured a second provincial title; however on that occasion Dublin defeated the men from the west in the All-Ireland SFC final. In 1964 Donnellan was appointed captain of the Galway team. That year he won a third Connacht title before leading his team out in the All-Ireland final against Kerry. Galway were victorious on that day by five points and Donnellan captured his first All-Ireland SFC medal. His moment of triumph was short-lived as, shortly after hoisting the Sam Maguire Cup, he learned that his father Michael had died in the Hogan Stand shortly before the start of the second-half.
In 1965 Donnellan added a fourth provincial medal to his collection. In the subsequent All-Ireland final against Kerry he was sent off but Galway were still victorious, giving Donnellan a second consecutive All-Ireland medal. The following year he won a fifth Connacht Championship title before qualifying for a fourth consecutive All-Ireland final appearance. Galway had a six-point win over Meath, thus giving Donnellan a third consecutive All-Ireland SFC medal and establishing that Galway team as one of the greatest of all time. In 1967 he won a Railway Cup medal with Connacht before winning a sixth and final provincial medal in 1968. Donnellan retired from inter-county football shortly after.
Political career
Donnellan's father Michael died suddenly in September 1964, and at the resulting by-election in December John was elected to Dáil Éireann as a Fine Gael TD for the Galway East constituency. He was successful at the next eight general elections, with changes of constituency; to Galway North-East in 1969, back to Galway East in 1977, and from 1981 to 1989 for Galway West.[3]
In April 1988, following criticism of party leader Alan Dukes, Donnellan was expelled from the parliamentary party.[6] Donnellan retired from politics at the 1989 general election.
