In 1910, the government rekindled its pre-revolutionary Russification campaign in an attempt to restrict minority rights, notably drastically curtailing Finland's autonomy. Most Kadets were opposed to these policies and allied with the left-wing of the Octobrists tried to blunt them as much as possible, but they were unsuccessful. However, a minority of Kadets headed by Pyotr Struve supported a moderate version of Russification, which threatened to split the party. With the increase in popular discontent after the Lena massacre on 4 April 1912 and a continuous decline in party membership after 1906, the rift in the party became more pronounced. Kadet leaders on the left like Central Committee member Nikolai Vissarionovich Nekrasov argued that the Duma experience had been a failure and that "constructive work" was pointless under an autocratic government. Kadet leaders on the right like Central Committee members Vasily Maklakov, Mikhail Chelnokov, Nikolai Gredeskul and Ariadna Tyrkova-Williams argued for a shift to the right. The disagreements were temporarily put aside in July 1914 at the outbreak of World War I when the Kadets unconditionally supported the government and found an outlet for their energies in various kinds of relief work under the umbrella of the All-Russian Union of Zemstvos and the All-Russian Union of Cities.
