"I was born in Equatorial Guinea when it was a Spanish colony," explains Rita Bosaho. "My parents died when I was very young, and I came to live with a foster family in Spain."

Bosaho's foster father was in the military, so they moved around, living in several Spanish cities. She was the only black child in a white foster family and in all of her schools, until university.

Compared with the rest of Europe, Spain is a relatively homogenous society. It has traditionally sent emigrants abroad, rather than receiving them, especially in the 1970s, when Bosaho was growing up. She is now 50.

She says she credits her foster parents with teaching her the values of equality and justice. She became a hospital nurse and volunteered with disadvantaged populations of Roma and other minorities in the rough northern barrios of Alicante, on Spain's Mediterranean coast.

Then, two years ago, when Spain's new left-wing political party, Podemos, began searching for diverse, accomplished people willing to go into politics, Bosaho signed up.

'Lots of people don't understand I'm Spanish'

In elections on December 20, 2015, she won a seat in Spain's parliament becoming the first person of color, male or female, ever to do so in modern Spanish history.

Bosaho is still coming to terms with her newfound fame.

"I feel humbled and proud, and hope I can empower minorities," she says. "There are lots of people who don't understand that I'm Spanish. They see that I'm black and think those two things can't go together."

But the Spanish population is changing. More than 10 percent are immigrants who've become Spanish citizens, though most are lighter skinned, from Latin America or Eastern Europe.

Spain received a wave of Latino immigrants in the 1990s, during its economic boom years, when there were ample jobs in construction and home health care. Spanish law allows citizens of most former Spanish colonies, many of which are in Latin America, to obtain Spanish passports within just two years.

Under-represented in politics

Some of those Latinos returned to their countries of origin after Spain's economy began faltering in 2008. Spanish unemployment remains stuck above 20 percent, and many immigrants worry they are over-represented in the jobless ranks while under-represented in politics.

At a recent community gathering in Valencia, on Spain's Mediterranean coast, immigrants from several Latin American countries packed into a local Podemos office to meet Bosaho, their new lawmaker.

"I'm so proud to see a woman, an African woman, no less, representing us in parliament," says Patricia Villalba, an unemployed 58-year-old originally from Ecuador. "Immigrants should be more visible in Spanish society."

Europe has struggled with an influx of migrants and asylum seekers that brought more than 1 million people to its shores in 2015, with more than 140,000 more following since January. Many are fleeing the war in Syria, but economic migrants have also joined their ranks.

Arab and African migrants and refugees typically want to go to more prosperous northern Europe, and while Spain has agreed to accept more than 17,000 refugees under European Union quota plans, just a small fraction of those have arrived from landing zones in Greece and Italy. Madrid's city hall is nevertheless draped in a "Refugees Welcome" banner.

Unlike in other parts of Europe, there is no major far-right, anti-immigrant political movement here, though racism exists. In 2014, a banana was hurled at a Brazilian soccer player in Spain's Villareal stadium, and spectators taunted a Spanish team's Senegalese player by making monkey noises.

Bosaho's own party, Podemos, has been criticized for promising dignity to unemployed protesters in the street but not yet backing that up with policy. Bosaho has yet to author any legislation. But she's changing perceptions about those who do.

The stereotype of a Spanish politician "is always a man, the typical white man," says Aitana Christensen Ribera, an 18-year-old high school student who met Bosaho when the lawmaker visited her high school. "And now you have her! That's the new politics."

But Bosaho is aware of the scope of the challenge she faces.

"People in Spain see me differently," she says. "And I worry they value me differently. How can I convince people I'm Spanish, just like them?"
