Outside of the U.S., some good news has occurred amidst a week that has otherwise been full of mayhem and chaos.

On Wednesday, the Dominican Republic’s Executive Branch approved a law that unilaterally bans child marriage in its country.

In the past, children younger than 18 were allowed to marry with a special exemption from a judge. These exemptions happened often. Now, no woman or man under the age of 18 are allowed to marry under any circumstances in the Dominican Republic.

This move is significant because the Dominican Republic has the highest rates of child marriage in Latin America and the Caribbean. Official government figures show that 36% of Dominican girls and adolescents marry or enter into “unions” before the age of 18. In 12% of these relationships, the female partner was less than 15 years old.

More informal “unions” where a girl simply moves into an older man’s household are also common in the DR. These are very common in higher poverty communities where many girls are considered a financial burden on their families. Unions like these will be harder to penalize because there is no formal documentation of their partnership.

There are multiple factors that play into the Dominican Republic’s high child marriage rate.

One of the main factors is the culture of machismo that informs the way that young men and women approach relationships.

According to research conducted by Plan International, 81% of Dominican girls said they preferred men that were five years older than them. This statistic is in stark contrest to 39% of Dominican men who prefer their partners 18 or younger because they found them more “obedient” and “adaptable”.

Not only that, but there is also a strong cultural expectation for girls and women to become mothers and wives. These cultural beliefs have simply stoked the practice of child marriage.

“Child marriage and early unions are seen as normal in society. It is driven by machismo that sees the role of a woman to be just a mother and wife,” said Rosa Elcarte, UNICEF’s representative in the Dominican Republic, to the Thomson Reuters Foundation. “Ending early unions will require years of work to change cultural norms.”

Feminists and human rights activists consider this law a win after many years campaigning to put an end to this practice.

But on a bittersweet note, many advocates realize that one law doesn’t dismantle the patriarchal structure of their culture that enabled this practice for so long. There is still a lot of work to be done.

“Our girls and adolescents will be protected … and cannot be forced into marriage in their childhood or adolescence, which in the past was often carried out by parents and legally allowed,” said Sonia Hernandez, an associate director of the International Justice Mission, in a statement to NBC News.
