In February 1636, Later Jin envoys led by Tatara Ingguldai visited Joseon Korea to participate in the funeral of their late Queen. However, as the envoys included 77 high-ranking officials from the recently conquered Mongolian tribes, the real purpose of the envoys was to boast the recent expansion of the Later Jin sphere of influence and examine the opinion of Joseon about the upcoming ascension of Hong Taiji as the "Emperor". The envoys informed King Injo about their ever-growing strength and requested celebration of Hong Taiji's ascension from Joseon.
