However, the textbook writers will steer clear of any controversy and give information from government sources.

The change in the syllabus comes in the wake of the implementation of the National Curriculum Framework, which suggests that the textbooks should connect knowledge to real life situations.

"You cannot teach Political Science to students sidestepping the major events, which had significant influence on society and polity, no matter whether controversial or not," Professor Yogendra Yadav, a member of the panel for preparation of Political Science textbooks, told PTI.

"So we are covering all the major happenings including Gujarat riots, Ayodhya incident, Emergency and many other controversies," he said.

The topics would give the established facts taken from government sources, which cannot be disputed by anybody, he said adding that the text would also refrain from going into full details of the incidents.

The chapter on Gujarat riots will deal with an overview of the incident and the large-scale killing of "people of a particular community," he said.

"The topic will also give a human rights view and a counterview on the incident," Yadav said, adding the textbook will be introduced in April 2007.

Earlier, the NCERT textbook did not include chapters on controversial incidents, but the approach has changed, Yadav said.

"You cannot keep the students away from learning controversial things. If they do not get information on such issues, they may look for the material from other sources. So it is better to give a clear and unbiased picture about the controversies," he said.

The textbooks will not discuss active political personalities but will only include events.

The other topics include Challenges of Communalism, Rise of OBCs in North-Indian politics, Challenges of and responses to Globalisation, democratic upsurge and coalition politics, United Front, National Democratic Alliance and United Progressive Alliance governments.

The book will have a chapter "Crisis of the Constitutional Order," which will highlight Emergency, its context, constitutional and extra-constitutional dimensions, and resistance to the Emergency, Navnirman movement of Gujarat and Bihar among other topics.

"The chapter will be free from any ideological bias. It will represent facts without any conclusion," he said.

The class XII students will also learn about Anti-Sikh riots of 1984, regional aspirations and conflicts, the Kashmir situation, challenges and responses in the northeast.

India's relations with other countries, Nehru's foreign policy, Sino-Indian war of 1962, Indo-Pak war of 1971, India's nuclear programme and development plans of the country after Independence will also find place in the textbooks, he said.

The book will also give a picture of contemporary world politics which will include Cold War era, US dominance in world politics, South Asia and post cold war era.
