A member of Westmorland’s dominant political dynasty, Lowther succeeded his father, Colonel Henry Cecil Lowther, as Conservative MP for the county in January 1868. Lowther’s grandfather was William Lowther, first earl of Lonsdale, who in 1802 had inherited the family’s vast estates in Cumberland and Westmorland. Before entering Parliament, Lowther enjoyed a distinguished career in the diplomatic service, which culminated in his appointment as minister plenipotentiary to Argentina in 1867, though, following the death of his father in December that year, he never took up the post, electing instead to offer for the vacancy at Westmorland.
In his published election address, Lowther conceded that the length of his diplomatic service had ‘deprived’ him of becoming ‘personally known’ to the electors, but insisted that ‘I bear a name which has from the earliest times been intimately associated with the county of Westmorland’.
Elected unopposed, Lowther had little time to make his mark in the Commons before the 1868 general election, though his two known contributions to debate prior to the dissolution reflected his chief concerns. He zealously defended the diplomatic service from accusations of abuse, arguing that no government department was ‘better or more efficiently administered’ than the foreign office, 26 May 1868, and during a debate on the public schools bill, he called for greater financial support for Westminster school, 7 July 1868. He also served on the 1867-68 select committee on scientific instruction.
Re-elected at the 1868 general election, Lowther spoke regularly in Parliament (unlike his father who had been known as the ‘silent colonel’) and continued to support Disraeli on most major issues, though ‘his diplomatic experience and his extreme fairness of mind kept him from being in any extreme sense a party man’.
