frugality, which impressed the people. Fearful of the intentions of the general Yuchi Jiong, who was then the commandant at Xiang Province (相州, roughly modern Handan, Hebei), he summoned Yuchi back to the capital. Yuchi, however, refused, and believing that Yang's intentions were to usurp the throne, rose at Xiang Province against Yang. He was supported by the generals Sima Xiaonan (), the commandant at Xun Province (勛州, roughly modern Xiaogan, Hubei) and Wang Qian (), the commandant at Yi Province (roughly modern Chengdu, Sichuan). However, just 68 days after Yuchi rose in rebellion, the general Wei Xiaokuan defeated Yuchi, and Yuchi committed suicide. Wang was also soon defeated, and Sima fled to Chen. To prevent Yuchi's headquarters at Yecheng to be used again as a base of opposition against him, Yang Jian had Yecheng (Northern Qi's old capital) torn down. During Yuchi's campaign, Zhou princes like Yuwen Xian Prince of Bi and Yuwen Zhao made attempts to assassinate Yang, but failed. In response, Yang put Yuwen Xian, Yuwen Zhao and Zhao's younger brother Yuwen Sheng () the Prince of Yue and their sons to death, and after Yuchi was defeated, he began to slaughter the Yuwen clan in earnest. He also had Emperor Jing promote his titles quickly, and he changed his surname back to Yang. Around the new year 581, his title was promoted to Prince of Sui (). In spring 581, he had Emperor Jing yield the throne to him, ending Northern Zhou and establishing Sui Dynasty, as its Emperor Wen. (His use of "Sui" as his new dynasty name was typical of Chinese historical dynastic transitions—using the old fief name as the new dynasty's name—but he, believing that the character for his fief Sui () to contain a "辶" radical, denoting "walking" and therefore a lack of permanence in the regime, removed "辶" from the character, rendering it "隋".) Early Kaihuang era Emperor Wen abolished Northern Zhou's governmental organization of six departments, instead establishing five main bureaus—executive bureau (Shangshu Sheng (), examination bureau (Menxia Sheng (), legislative bureau (Neishǐ Sheng (), Palace Library, and eunuch bureau (Neishì Sheng (內侍省—note different tone and character versus 'legislative bureau')), with two additional independent agencies, 11 other independent departments, and 12 military commands. He posthumously honored his father Yang Zhong and mother Lady Lu as emperor and empress. He created his wife Duchess Dugu empress and their oldest son Yang
