King Willem-Alexander became the first male monarch of the Netherlands in more than a century Tuesday as his mother Beatrix abdicated to end a 33-year reign. The generational change in the House of Orange-Nassau gave the Netherlands a moment of celebration and pageantry, according to a report of the Associated Press. "I am happy and grateful to introduce to you, your new king, Willem-Alexander," she said. The former queen becomes Princess Beatrix and her son becomes the first Dutch king since Willem III died in 1890.
