• Social divisions have a vast impact on politics. Social divisions along with political trends can be very risky.
• Democracy involves a rivalry between different political parties.
• As their rivalry tends to divide society, if they start competing in terms of any established social differences, then it can turn those social divisions into political divisions, which can lead to confrontation, violence, and even country disintegration.
• Social divisions affect politics in both negative as well as positive ways. 

Social divisions affect politics in negative ways as follows:

• Social division along with political division is very risky and dangerous.
• The rivalry between political parties leads to the division of society.
• If political parties compete in terms of certain social differences, it leads to social conflict, violence, and even disintegration of the country.
• The disintegration of Yugoslavia into six independent countries is the best example of the negative impact of social division(division on the basis of religion and ethics).
• There has been a violent and bitter ethnopolitical struggle going on in Northern Ireland for many years (religious divisions led to ethnopolitical conflict).

Social divisions affect politics in positive ways as follows:

• The political representation of social inequalities helps exploited and oppressed social classes to voice their concerns and demand rectification from the government.
•  In a democracy, political parties raise concerns about these divisions,
  make policies to redress the grievances of the disadvantaged communities.
• In most countries too, social differences influence voting. Individuals from one group are more likely to support certain factions than others.
• If there are no social divisions in any country, it’s a great thing.
• Hence, social divisions do not always lead to disintegration of the country.
