In March 1911, he introduced the second reading of the Coal Mines Bill to parliament, which—when implemented into law—introduced stricter safety standards to coal mines. He also formulated the Shops Bill to improve the working conditions of shop workers; it faced opposition from shop owners and only passed into law in a much emasculated form. To maintain pressure on this issue, he became president of the Early Closing Association and remained in that position until the early 1940s. In April, Lloyd George introduced the first health and unemployment insurance legislation, the National Insurance Act 1911; Churchill had been instrumental in drafting it. In May, his wife gave birth to their second child, Randolph, named after Churchill's father. In 1911, he was tasked with dealing with escalating civil strife, sending troops into Liverpool to quell protesting dockers and rallying against a national railway strike. As the Agadir Crisis emerged, which threatened the outbreak of war between Germany and France, Churchill suggested that—should negotiations fail—the UK should form an alliance with France and Russia and safeguard the independence of Belgium, the Netherlands, and Denmark in the face of possible German expansionism. The Agadir Crisis had a dramatic effect on Churchill and his views about the need for naval expansion.
