A political party is a group of people who come together to contest elections and hold power in the government. They agree on some policies and programmes for the society with a view to promote the collective good. Since there can be different views on what is good for all, parties try to persuade people why their policies are better than others. They seek to implement these policies by winning popular support through elections.
Thus, parties reflect fundamental political divisions in a society. Parties are about a part of the society and thus involve PARTISANSHIP. Thus a party is known by which part it stands for, which policies it supports and whose interests it upholds. A political party has three components:
The necessity of political parties can be understood by imagining a situation without parties. Every candidate in the elections will be independent. So no one will be able to make any promises to the people about any major policy changes. The government may be formed, but its utility will remain ever uncertain. Elected representative will be accountable to their constituency for what they do in the locality. But no one will be responsible for how the country run.
The rise of political parties is directly linked to the emergence of representative democracies. As we have seen, large scale societies need representative democracy. As societies became large and complex, they also needed some agency to gather different views on various issues and to present these to the government. They needed some way to bring various representatives together so that a responsible government could be formed. They needed a mechanism to support or restrain the government, make policies, justify or oppose them. Political parties fulfill these needs that every representative government has.
So, it can be said that parties are a necessary condition for a democracy.
