(AP) -- The Walt Disney Co. is defending its newest princess following a backlash over her Hispanic-influenced ethnicity.

A new character named Sofia will star in the TV movie "Sofia the First: Once Upon a Princess" airing Nov. 18 on the Disney Channel and Disney Junior. Hispanic advocacy groups have questioned whether the fair-skinned, blue-eyed young princess is an accurate representation of the Hispanic population and wondered why Disney isn't doing more to promote its first princess with Hispanic-inspired roots.

"They seem to be backpedaling," said Lisa Navarrete, spokeswoman for the National Council of La Raza. "They've done such a good job in the past when they've introduced Native American, African-American and Asian princesses. They made a big deal out of it, and there was a lot of fanfare, but now they're sort of scrambling. It's unusual because Disney has been very good about Latino diversity."

Craig Gerber, co-executive producer of "Sofia the First," clarified in a Facebook post on Friday that Sofia is "a mixed-heritage princess in a fairytale world." He said her mother and birth father respectively hail from kingdoms inspired by Spain and Scandinavia, though Sofia was born and raised in Enchancia, a "make-believe 'melting pot' kingdom" patterned after the British Isles.

Sofia is voiced by Caucasian "Modern Family" actress Ariel Winter, and her mother is played by Hispanic "Grey's Anatomy" actress Sara Ramirez.

The film and a subsequent TV series will follow the young princess as she adjusts to royal life after her mother marries the king of Enchancia.

"Sofia considers herself a normal Enchancian girl like any other," said Gerber. "Her mixed heritage and blended family are a reflection of what many children today experience."

Inez Gonzalez, executive vice president of the National Hispanic Media Coalition, said Monday that the organization wanted to meet with Disney to discuss "Sofia the First."

"Sofia's world reflects the ethnically diverse world we live in, but it is not our world," said Nancy Kanter, senior vice president of original programming for Disney Junior. "It is a fairytale and storybook world that we hope will help spur a child's imagination. It's one where we can have flying horses, schools led by fairies, songs that have a Latin beat and towns with markets like those found in North Africa."

Kanter added that the "Sofia the First" series set to debut next year would include storylines about a holiday called Wassailia, which is reminiscent of a Scandinavian Christmas; and the characters would go on a picnic in Wei-Ling, an Asian-inspired kingdom.

Marcela Davison Aviles, president of the Mexican Heritage Corporation, said that calling Sofia a Latina princess is "not an accurate use of the term as many in our community understand its meaning." Davison Aviles has worked with Disney on the TV series "Handy Manny," which features a bilingual Hispanic handyman character. She added that "Disney leadership embraces the complexity, diversity and beauty" of the Hispanic community.

"I'll bet folks at the company are using this as a teachable moment to improve on that effort," said Davison Aviles. "I'm looking forward to meeting Sofia and to Disney's future efforts to illuminate our diverse melting pot, including the varied colors which thread our tapestry of Latino identity."

Over the past two decades, Disney has introduced such culturally diverse female protagonists as Jasmine, Pocahontas, Mulan, Merida and Tiana, the African-American princess from 2009's "Princess and the Frog." Disney's 2000 animated film "The Emperor's New Groove" and its subsequent spin-offs were set amid the Incan Empire in South America.

"Little girls look to these characters to see themselves represented," said Navarrete. "If they don't see themselves, it makes a difference. It would be nice to see Disney make a full-out push for a Latina princess, whether it's 'Sofia the First' or not."
