武则天，中国历史上唯一的女性皇帝，她执掌权力的岁月饱经风霜，享受了悠久的统治年限。作为一个优秀的女性领导者，她以其智慧和勇气在历史舞台上留下了深刻的印记。那么，武则天到底当了多少年的皇帝呢？

公元690年，武则天登基为唐朝的皇后，仅仅过了两年，公元692年，她便以太后身份掌握了实际的政权。此时，武则天已经开始运用聪明才智和政治手腕来巩固自己的地位。她精于权谋，在位期间稳定了国家的政治局势，促进了社会的繁荣和发展。

From the year 690, Wu Zetian ascended to the throne as the Empress of the Tang Dynasty. After just two years, in 692, she took control of the actual political power as the Empress Dowager. At this point, Wu Zetian began to use her intelligence, political strategies, and skills to consolidate her position. She excelled at power tactics and during her reign, she stabilized the political situation of the country, promoting prosperity and development in society.

公元705年，武则天决定改元，正式成为皇帝。她废黜了自己的儿子，太子李重茂，将他囚禁在宫中，并以病痛为名正式继位。此时，武则天开始以帝王之姿统治国家，堪称中国历史上第一个女皇帝。

In the year 705, Wu Zetian made the decision to establish her own dynasty and became the Empress. She dethroned her own son, Crown Prince Li Chongmao, imprisoning him in the palace, and officially ascended to the throne under the pretext of illness. From this point on, Wu Zetian ruled the country as an emperor, becoming the first and only female emperor in Chinese history.

公元710年，武则天年逾80，在位长达16年的她决定退位，让位给侄子李显，即唐中宗。虽然退位，但是她仍然保留着相当的权力，继续干预政务，并在政治上对中宗施加影响。

In the year 710, at the age of over 80, after a reign of 16 years, Wu Zetian decided to abdicate the throne and pass it on to her nephew, Li Xian, who later became Emperor Zhongzong of Tang Dynasty. Although she stepped down from the throne, she still retained considerable power, continuing to intervene in political affairs and exerting influence over Emperor Zhongzong.

武则天最后一次登基为皇帝是在公元705年，而她退位的时间是在公元710年。因此，她作为皇帝的统治年限为5年。

Wu Zetian's final ascension to the throne as an emperor was in the year 705, and she abdicated in the year 710. Therefore, her reign as an emperor lasted for 5 years.

武则天通过她的卓越领导能力和政治技巧，成为中国历史上一个重要而又独特的才女统治者。她的统治年限虽然不算长久，但她对国家的发展和社会的进步作出了卓越的贡献。

Through her exceptional leadership abilities and political skills, Wu Zetian became an important and unique female ruler in Chinese history. Although her reign was not lengthy, she made outstanding contributions to the development of the country and the progress of society.
