Despite being warned by respected historian R. Bruce Winders that the description was simplistic and inaccurate, the network ran the piece.
"We recognize that there were several key issues in the Battle of the Alamo and one of them was slavery," said Mark Lyons, a senior producer for Nick News at Lucky Duck Productions in New York, which contracts for the Viacom Inc.-owned network.
Texas declared independence in 1836 when Mexico's leader, Gen. Antonio Lopez de Santa Anna, revoked the existing cons ution that allowed white settlement of the nation's northernmost province.
"The slavery issue was a factor but not the main one," Winders wrote Nickelodeon prior to the piece airing. "The revolt in Texas started as an effort to restore the Federal Republic under the (Mexican) cons ution of 1824, but quickly evolved into a separatist movement."
About 200 Texan fighters held off thousands of Mexico troops for 13 days until Santa Anna finally crushed them on March 6, 1836. However, the siege gave other Texas units a chance to move east and gather for an ultimately pivotal battle near Houston in April 1836 that secured Texas independence.
