Study shows female monarchs more likely to start wars than males

'"People have this preconceived idea that states that are led by women engage in less conflict," says Oeindrila Dube, an assistant professor of politics and economics at New York University. But historically, that's just not true. Not only did queens fight more wars than kings, they were also more likely to start them, Dube and NYU Ph.D. candidate S.P. Harish show in research presentedSaturday at the American Political Science Association's 2015 annual meeting in San Francisco.

Overall, women are less violent than men—they commit fewer than 1/10th of the murders in the United States—and, when elected to office at the local level, enact different policies than their male counterparts. But on the global stage, perhaps women can be more aggressive—Margaret Thatcher and Indira Gandhicertainly were. But were Thatcher and Gandhi just particularly aggressive women who fought their way to power and then on to war? Or would many other women in power do the same thing?

To wade through the questions, Dube and Harish focused on a group of women who landed in power not through hard work or even by choice, but rather by birth: queens. If queens were less likely than kings to get involved in war, the researchers posited, then maybe getting more women in leadership positions today would reduce global conflicts.'
