A member of the Catholic gentry of county Tipperary, Lanigan was, from 1830, land agent to Robert Otway Cave. He came into possession of a small estate at Glenaguile, four miles east of Nenagh, where his family had been ceded land by Lord Orkney in the early eighteenth century, and inherited Richmond House through marriage.
Lanigan had commenced his political career by establishing a branch of the Catholic Association in Tipperary with an elder brother, Martin Lanigan (c.1795-1830), a barrister and the leader of the Independent Freeholders of the county, who was credited with engineering the return of Thomas Wyse for Tipperary in 1830.
The Conservatives were confident that Lanigan could ‘be managed’, but he divided with the Liberals to bring down the Derby ministry, 10 June 1859, and opposed Disraeli’s motion on the income tax, 24 Feb. 1860.
Lanigan is not known to have brought forward any bills or served on any select committees, but he frequently asked parliamentary questions of ministers.
In March 1860 Lanigan highlighted his career’ by launching a powerful protest against the removal of Irish paupers from Great Britain, an intervention which led directly to the passing of the Poor Removal Acts in 1861.
Lanigan was also involved with the public campaign for denominational education, being one of 19 MPs to address the Irish chief secretary on the subject in August 1860. He supported Cardinal Cullen’s opposition to the government’s national education reforms and in 1862 denounced the Queen’s Colleges as ‘nurseries of infidelism’.
A keen sportsman, racehorse owner and steward of the Templemore and Cashel races, Lanigan had on one occasion intervened personally to avert a serious collision between local people and soldiers of the Templemore garrison during a race meeting held on his farm in 1856.
