Okay, this one has significantly lower quality, since I can't find any way to import the full image. So here's 1912:
January:
On January 1 Sun Yixian was declared Provisional President of the Republic of China, with his capital in Nanjing. However, although rebellions in Xinjiang attempted to spread the revolution there, his control was limited to areas that had rebelled against the Qing government last autumn.
February:
Prior to this point the New Army under Yuan Shikai had been the only thing propping up the Qing. This ended on 12 February, when Yuan decided to align himself with Sun's government and depose the last Qing emperor. Meanwhile the Tannu Uriankhai region of Mongolia seceded and declared itself a Russian protectorate, although Russian troops would not arrive until 1914.
March:
Yuan and Sun agreed to the North-South Compromise in early April: Yuan agreed to join the new Republic and be declared its president, but the capital of China would be moved to Yuan's power base at Beijing. Almost immediately the seeds of the later warlord era were planted, with most provinces being put under a dual military-civilian leadership that allowed many military officers to achieve a high level of autonomy under the government in Beijing.
April:
Chinese military rule in Tibet had been decidedly precarious following the unrest during the Xinhai Revolution, and in early 1912 the Tibetan leadership officially declared independence, with official recognition from the fellow secessionist government of Mongolia and de facto recognition by the United Kingdom. The Ma Clique that had risen to prominence in the late Qing Dynasty also established itself in Kansu under the new regime.
September:
Tan Yankai establishes a Xiang Clique in Hunan and is appointed as both military and civil governor of the province.
