Even though her reign was much maligned, Margaret Thatcher remains one of the most recognizable and resilient leaders of the 20th century. She is certainly one of the UK’s most famous leaders, and her premiership was defined by the notion that each citizen should take individual responsibility for their actions and the circumstances of their life. Once quoted as saying that anyone who finds themselves on a bus beyond the age of 26 can be counted as a failure, she sought to create a resilient nation that was driven by the principles of independence, capitalism and entrepreneurship.
