In May 1912 the formal merger of the Conservatives and Liberal Unionists was finally accomplished to form the Conservative and Unionist Party, now usually called the Conservative Party. Although by 1912 the political distinctions between the two parties had long ceased to have any real meaning, they had been a residual factor in Austen Chamberlain's failure to become the Unionist leader in the House of Commons in 1911. When Arthur Balfour resigned, Austen Chamberlain and Walter Hume Long both declared themselves as candidates for the leadership of the Unionist Party in the Commons. However, as Austen Chamberlain was still officially at least a Liberal Unionist, his candidature was opposed by many Conservatives, because they already had the Liberal Unionist Lord Lansdowne leading them in the House of Lords. In the end, Bonar Law was elected unopposed by Unionist Members, and Austen Chamberlain would have to wait ten years for his chance to lead the united party.
