A businesswoman, a mother of four, an international fashion icon（偶像） , a woman committed to making the world a better place for women and children—Queen Rania of Jordan is truly changing the world．

Rania was bom in Kuwait, in 1970．Shortly after Iraq invaded that country in 1990, her family fled and settled in Jordan．After graduating from a business school, Rania became successful in the business world．

When she was just 22, she went to a dinner party that changed her life forever．It was there that she met Jordan' s Prince Abdullah．Six months later, Rania and Abdullah had a royal wedding and started a family．

After the death of her father – in – law, King Hussein, in 1999, Prince Abdullah was crowned King Abdullah II of Jordan, and Rania became the world' s youngest living queen．

In her role as Queen, Rania has become well known around the world for her charity work and her efforts to improve educational opportunities for girls．She is an outspoken advocate of women' s rights, education reform, and child abuse．She is also well - known for her efforts to remove Western stereotypes （旧观念） about the Muslim world．

Rania explains that there is a direct relationship between increasing education and eliminating poverty．" You can change the course of a nation through education," she says．" One of the most important things you can do for a girl is empower her with her education．Once she has the education she can then have control over her income, she can change her life, she can have choices．"

In the future, Rania says, she hopes for a more open and secure world．"We look at problems happening halfway across the world and we think,' Well, that' s their problem．' But it' s not," she says．" When you solve somebody else' s problem, you are solving a problem for yourself, because our world today is so interconnected．"
