Rise of Neville Chamberlain in 1914 prevented implementation of his plans in Birmingham. With the outbreak of World War I in August 1914, Chamberlain became deeply involved in the war effort. In addition to his duties as councillor, Chamberlain helped recruit men for the Royal Warwickshire Regiment and set up funds for injured soldiers. Late in 1914, he became an alderman of Birmingham, and the following year, became Lord Mayor. Chamberlain's biographer, Robert Self, suggested that as Joseph Chamberlain had died the previous year, the honour was due to Neville Chamberlain's hard work rather than to any family influence. As a Lord Mayor in
Lord Chamberlain that the chamber reflected the royal tastes, the Lord Chamberlain received commands directly from the sovereign to be transmitted to the heads of subordinate departments. In 1594, the Lord Chamberlain, Henry Carey, 1st Baron Hunsdon, founded the Lord Chamberlain's Men, for which William Shakespeare was a part (and later a shareholder in the company) and for whom he wrote most of his plays during his career. Carey served under Elizabeth I of England at the time and was in charge of all court entertainment, a duty traditionally given to the Master of the Revels, a deputy of the Lord Chamberlain.
