Following the introduction of this programme the policy of protection was eventually ended and the Control of Manufacturers Act, which had been in place since 1932 and had been introduced by Lemass himself, was also abolished.

In the aftermath of this episode, the southern government under Seán Lemass, himself an IRA veteran of the War of Independence and Civil War, tried to forge closer ties with the authorities in Northern Ireland in order to promote peaceful cooperation on the island.

O ' Malley seems to have made this decision himself without consulting other ministers, however, he did discuss it with Lemass.

Lemass also encouraged Colley, Haughey and Blaney to withdraw in favour of Lynch, realising that they would not win the contest.

It was Lemass who encouraged him to stay and form a political party.

In the 1960s the economy greatly expanded, under the leadership of Seán Lemass, many rehousing schemes ( including Ballymun ) were started to clear the Dublin tenements ; the Industrial Development Authority refocused on high technology and foreign direct investment was encouraged.

In 1962 Lemass appointed Haughey as Minister for Agriculture.

De Valera appointed Lemass as Minister for Industry and Commerce, one of the most powerful offices in the Executive Council ( cabinet ), and a position he would occupy in every de Valera government.

De Valera became Taoiseach, while Lemass served in the new Government ( the new name for the cabinet ) again as Minister for Industry and Commerce.

Lemass became Minister for Supplies in 1939 following the outbreak of World War II ( known in Ireland, or Éire, as The Emergency ).

Lemass again returned as Minister for Industry and Commerce.

Lemass returned as Tánaiste and Minister for Industry and Commerce.

Lemass appointed several young and intelligent men to the post of Minister for Education, including Patrick Hillery and George Colley.

This plan had the backing of Lemass, however, O ' Malley never discussed this hugely innovative and hugely expensive plan with any other cabinet ministers, least of all the Minister for Finance Jack Lynch.

Lynch was promoted to Lemass ' old portfolio as Minister for Industry and Commerce.

He then served as Minister for Lands in de Valera's 1957-59 cabinet ; as Minister for Transport and Power under Seán Lemass ; and, successively, as Transport Minister, Posts and Telegraphs Minister, and Health Minister under Jack Lynch.

The economic war ended in 1938 with the signing of the Anglo-Irish Trade Agreement between both governments, after a serious of talks in London between the British Prime Minister Neville Chamberlain, de Valera, Ryan and Sean Lemass.

In a clear message that there would be a change in economic policy Ryan, a close ally of Seán Lemass, was appointed Minister for Finance, replacing the conservative Seán MacEntee.

In 1939 World War II broke out and a cabinet reshuffle resulted in MacEntee being appointed Minister for Industry and Commerce, taking over from his rival Seán Lemass.

A cabinet reshuffle in 1964 saw Lenihan join the cabinet of Seán Lemass as Minister for Justice.

The government was able to take control of the economic life of the country under the new Minister of Supply Seán Lemass.

In 1965 Faulkner was appointed Parliamentary Secretary to the Minister for the Gaeltacht by the Taoiseach, Seán Lemass.

Hillery was invited by Lemass to allow his name to go forward for the leadership of the party, however, he declined explaining that he had no interest.

But the state-run Telifís Éireann, facing criticism from Lemass ' government for being too radical in other areas, agreed and largely ignored the O ' Higgins campaign.

A veteran of the 1916 Easter Rising, the War of Independence and the Civil War, Lemass was first elected as a Sinn Féin Teachta Dála ( TD ) for the Dublin South constituency in a by-election on 18 November 1924 and was returned at each election until the constituency was abolished in 1948, when he was re-elected for Dublin South – Central until his retirement in 1969.

On 18 November 1924 Lemass was elected for the first time as a Sinn Féin TD.

Lemass travelled around the country trying to raise support for Fianna Fáil.

In 1933, Lemass set up the Industrial Credit Corporation to facilitate investment for industrial development ; in the climate of the depression investment had dried up.

Lemass was confined to the Opposition benches for another three years.

A generation of leaders who had dominated Irish politics for over three decades had moved off the stage of history — although neither Fine Gael or Labour's new leaders initiated major policy changes on the level of Lemass '.

Although the White Paper entitled " Economic Development " was first introduced in 1958 in de Valera's last government, its main recommendations formed the basis for the First Programme for Economic Expansion, which was adopted by Lemass as government policy upon his ascension in 1959.

While Aiken was at the UN, Lemass played a major role in pressing for Ireland's membership of the EEC which in many ways became the chief foreign policy consideration during the 1960s.

Lemass, who had served his country for fifty years, now retired to the backbenches.

One story exists where Lynch, in spite of tremendous pressure from Seán Lemass and the entire Fianna Fáil party to stand for the leadership, only accepted the nomination after Máirín had agreed.

Lemass had the two difficult tasks of developing Irish industry behind his new tariff walls, and convincing the conservative Department of Finance to promote state involvement in industry.

Lemass, along with T. K. Whitaker as Secretary for the Department of Finance set specific plans for economic growth, including planned investment in industrial infrastructure and dropping of many protective tariffs and giving tax incentives to foreign manufacturing companies to set up in Ireland.

When Seán Lemass succeeded de Valera as Taoiseach in 1959 Ryan was retained in the Finance portfolio.

He served in the governments of Éamon de Valera and Seán Lemass in a range of ministerial positions, including Finance, Industry and Commerce, and Health.

Lemass was appointed Parliamentary Secretary to the Minister for Finance, serving from 1969 until 1973 and holding responsibility for the Board of Works.
