As a great maritime and colonial power in centuries past, France relished its role in taking its culture to the far corners of the globe -- French schools, language, trade, modern medicine and various other trappings of its civilization.

But people in those places were not always happy with what accompanied the French largess, including war, slavery, torture and the eradication of their cultures.

Those competing views of history have set off an emotional debate in France and places it colonized, following passage of a law here mandating that French schools give more emphasis to the positive aspects of French colonization.

Critics call the law an effort to obscure abysmal treatment of blacks and other indigenous peoples during colonial times and suggest that it mirrors a similar attitude toward immigrants in France today.

The link between the eras "is very, very great discrimination," said Victorin Lurel, a socialist member of Parliament from the French Caribbean island of Guadeloupe. "The youngsters in the suburbs are sons of immigrants -- they are colored and blacks and Algerian, and their parents were discriminated against in French society, and that is one motivation that was at the foundation of the violence and riots in the suburbs" that rocked France for three weeks in October and November, he said.

The law is part of an otherwise uncontroversial bill that Parliament passed in February to improve conditions for French people who left Algeria after independence there and moved to France.

The language in question calls for French school programs to "recognize in particular the positive role of France's presence overseas, notably in North Africa, and give due prominence to the history and sacrifices of French army fighters from these territories."

"I wanted to pay homage to all the troops from our overseas territories who fought so valiantly for France during World War II," the measure's sponsor, Christian Vanneste, said in an interview, "and to pay tribute to the one million Frenchmen and some 150,000 repatriates who had to leave Algeria in 1962."

The bill generated criticism in France and its former colonial realm at the time, and the debate was reignited after Parliament reaffirmed the law two weeks ago.

Some history teachers and left-wing politicians contend that conservatives were trying to legislate away massacres and torture perpetrated by French troops during Algeria's 1954-62 war of independence and to whitewash France's role in the slave trade and the subjugation of indigenous cultures in the Caribbean.
