When Fianna Fáil came to power in 1932, Boland became a perennial member of the cabinet, most notably as Ireland's longest-serving Minister for Justice.
Gerald and his brothers Harry and Ned subsequently joined the Irish Volunteers when that organisation was established in 1913, serving in the same company as Arthur Griffith.
When news broke out of the Easter Rising in 1916 Boland immediately left his job in Crooksling, however, he was bitterly disappointed when he found out that the order was countermanded.
[3] Boland was released after a general amnesty in December 1916, however, he remained involved in revolutionary circles, although he declined to rejoin the IRB, believing the organisation was no longer needed.
On the outside, his brother Harry died some days after being shot, in August 1922, after two National Army officers attempted to arrest him at the Grand Hotel in Skerries, Dublin.
Shortly after this split, a new party emerged called Fianna Fáil, with de Valera acting as leader and the other disillusioned Republican TDs joining.
Fianna Fáil remained in power with an increased mandate following the 1933 general election and Boland was promoted to the position of Minister for Posts and Telegraphs.
Boland was critical of Lemass' policy of centralising industrial development in Dublin, he instead wished to see a more decentralised economy based around food production.
[3] In 1937 Boland was highly vocal during the drafting of a new constitution of Ireland by Fianna Fáil against any word which would have given the Catholic Church special status, something heavily considered at the time.
Boland declared that if the constitution elevated the position of the Catholic Church above others, it would be sectarian, anti-republican, and a hindrance to any prospects of Irish reunification.
[3] The outbreak of World War II in 1939, known as the Emergency in Ireland, resulted in several new cabinet appointments and Boland became Minister for Justice.
Boland subsequently introduced tougher measures by setting up a military court with the death penalty with no provision for appeal except for a review by the government.
Boland and Fianna Fáil felt their hardline was backed by the electorate following strong returns for the party at the 1944 general election.
Led by Seán MacBride, this new party sought to kick off a new post-war political era in Ireland, and to do this meant removing Fianna Fáil from power.
Many in Clann na Poblachta had Republican backgrounds and in some ways, the party could be partially described as an organic reaction to Fianna Fáil and Boland's hardline stance during the war years.
Many in political circles, including inside Fianna Fáil, thought Clann na Poblachta could be a new force to reckon with.
The coalition saw Clann na Poblachta forced to work with Fine Gael, considered the traditional "enemy" of Irish Republicanism.
By 1951 the coalition collapsed and Fianna Fáil returned to government following that year's election, with Boland re-appointed Minister for Justice.
In 1970, the outbreak of the Arms Crisis saw Kevin Boland resign as a Minister and as Secretary of Fianna Fáil in protest at the government's policy on Northern Ireland and in response to the sackings of Charles Haughey and Neil Blaney from the cabinet over allegations they had arranged for weapons to be provided to the Provisional IRA.
Gerald Boland, in a similar protest, resigned as a vice president and as a trustee of Fianna Fáil, although he remained a member of the party.
