The answer is 'majority'.

Explanation:
The Radicals were a political group in the 19th century who believed in the principles of democracy, liberty, and equality. They believed that the government should be based on the will of the people, and that the majority should have the power to make decisions for the whole nation. Here are some points to explain this answer in detail:

• The concept of majority rule is an essential part of democratic governance. In a democratic system, decisions are made by the majority of people, who elect their representatives to make laws and policies on their behalf.

• The Radicals believed that the government should be representative of the people it governs. They believed that the majority of people should have a say in how the government functions, and that the government should work towards the welfare of the majority.

• The Radicals believed that a government based on the majority would be more just and equitable than a government that catered to the interests of a minority. They believed that a government that represented the majority would be more responsive to the needs of the people, and would be more effective in delivering public services and goods.

• The concept of majority rule also implies that the minority should be protected from the tyranny of the majority. The Radicals believed that the government should have checks and balances to ensure that the rights and interests of the minority are not trampled upon by the majority.

• The Radicals believed that the government should be accountable to the people it governs. They believed that the majority should have the power to choose their representatives, and to hold them accountable for their actions.

In conclusion, the Radicals wanted a government that was based on the majority, as they believed that such a government would be more just, equitable, and responsive to the needs of the people.
