I have never given an extensive thought for my list, but off the top of my head, here is my list for people from Chinese history.
Assassins allies:
•Zhuang Zhou — I imagine him to have been a proto-Assassin because his philosophy was very similar to the Creed
•Zhang Liang
•Liu Bang (Emperor Wu of Han)
–Since he and his friends are thought to have fit the class of people called youxia, his story seems fitting for an Assassin tale, but his heart was never truly committed to Assassin principles. Once he became the first Han emperor, he quickly fell into paranoia and turned on most of his former allies and friends.
•Liu Heng (Emperor Wen of Han) and Empress Dou Yifang
•Liu Ju, Crown Prince to Emperor Wu of Han
•Liu Bingyi, Emperor Xuan of Han
•Liu Bei, Zhuge Liang, Guan Yu, Zhang Fei, etc. as Assassins in their own right, not just allies.
–Liu Bei's legend is situated in the traditional genre of youxia, the wandering, assassin adventurer hero, so this only make sense. I really do not like Zhang Fei, but as Liu Bei's sworn brother, it only makes sense he would be an Assassin as well.
•Li Shimin, Emperor Taizong of Tang
•Li Zhi, Emperor Gaozong of Tang — I imagine he was originally meant to be an Assassin ally upon succeeding his father but came under the influence (and poison) of Wu Zetian
•Li Xian, Emperor Zhongzong of Tang — restored the Tang after Wu Zetian
•Empress Wei and her daughter Princess Anle (Li Guo'er)
— History writes that they corrupted the court, murdered Emperor Zhongzong to try to make Princess Anle Empress Regnant, and that they were ultimately killed by the faction of Li Longji (Emperor Xuanzong of Tang). Even real-life historians nowadays think this account might be fabricated, which I would like to believe so due to conflicting accounts of how loving they were to Emperor Zhongzong during the days they lived in fear from Wu Zetian. Some historians also think that Li Longji's coup was effectively a battle of patriarchy over the trend of female empowerment that was reaching a peak in this time. I think this would make a fascinating case of very successful Templar rewriting of history.
•Princess Taiping
–Ally of Li Longji during his coup but became his chief political rival afterwards. She also lost and was executed. History is, again, muted on their ideological differences. I would like to imagine that either Empress Wei and Princess Anle were Assassin allies or Princess Taiping was (but not both). As the daughter of Wu Zetian though, it stands to reason that she may have been a Templar instead.
•The Song dynasty in general
•Zhu Yunwen, the Jianwen Emperor
•Martin Lee, Nathan Law, Joshua Wong, Agnes Chow, Denise Ho, et al. #MilkTeaAlliance :)
•Tsai Ing-wen
Templar allies and puppets:
•Shang Yang
•Han Fei
•Qin Shi Huang
•Liu Bang (Emperor Gaozu of Han), I like to think of him as initially being supported by the Assassins but then falling into paranoia by the machinations of the Templars towards the end
•Empress Lü Zhi, wife of Liu Bang, possibly as a member of the Order of the Ancients herself
•Liu Che (Emperor Wu of Han), as a major Templar puppet but not a conscious ally
•Wang Mang
– Great case of an idealistic, revolutionary Templar rather than one who wanted to use the status quo for the sole sake of control
•Liang Ji
•Cao Cao and his family as Templars in their own right, not just an ally or puppet
–I think Cao Cao, as an anti-villain, ideologically fits the archetypal and idealized Templar mold more than any other Chinese figure in history; philosophically, he was very much akin to Haytham Kenway
•Li Zhi (Emperor Gaozong of Tang), a puppet by way of Wu Zetian
•Wu Zetian, founder of the Golden Turtles
•Di Renjie, one of the most celebrated detectives in Chinese history
•Lai Junchen
– Head of secret police under Wu Zetian, more in the vein of a Micheletto Corella
•Li Longji (Emperor Xuanzong of Tang)
– Already established as an unwitting Templar puppet in Assassin's Creed: Dynasty. Despite my aforementioned criticisms of him, I have always agreed with Dynasty's portrayal of him as at most a Templar puppet, not even a willing ally. I think in his youth, he may have received Templar help unwittingly. Alternatively, if Princess Taiping were a Templar instead and Empress Wei and Princess Anle not Assassin allies, his ousting of Princess Taiping could represent a temporary Assassin victory.
•Princess Taiping
–As daughter of Wu Zetian, her being a Templar is pretty likely, but I think there's a lot of opportunity for complex twists to her story
•Qin Hui
•Jia Sidao — this chancellor basically ensured that Emperor Duzong literally did not bother to help defend against the Mongol conquest at all for whatever reason lost to history, leading to the Fall of Xiangyang after a six-year siege where the defenders waited and waited and waited.... Since the later Mongol khans are Templars, I think it makes sense that this was a Templar agent.
•Zhu Yuanzhang, the Hongwu Emperor
•Zhu Di, the Yongle Emperor
•Mao Zedong
•Deng Xiaoping
•Xi Jinping, et al.
I will note that this is my conservative list for Chinese history, meaning that I was cautious about throwing historical leaders I liked straight in to the Assassin category and throwing those I disliked into the Templar category. There were many problematic and tyrannical Chinese rulers who I refrained from matching with the Templars because I do not think that every dictator or tyrant in history should have to be Templars. I was especially hesitant with the rulers from the Jin to the Sui dynasty even though I'm sure there must have been a Templar there somewhere. The choices I made here are heavily informed by what I know of the individual's ideology, alliances, and/or how it would fit into the narrative.
For a list of figures outside Chinese history very much just off the top of my head:
Assassins: Victor Hugo
Templars: Konoe Fumimaro, Tōjō Hideki, Tanaka Kakuei, Ōhira Masayoshi, Henry Kissinger, Richard Nixon, Margaret Thatcher, Ronald Reagan, George W. Bush, Vladimir Putin, Enver Hoxha, Kim Il-sung, Pol Pot, etc.
For the USSR, I think it makes sense that Joseph Stalin was a Templar, but the USSR ceased to be under Templar control when de-Stalinization occurred under Nikita Khruschev. Of course, this did not mean that the USSR ceased to be authoritarian, demonstrating that cutting out the Templars does not necessarily lead to liberalization or tremendous progress in human rights.
