Step 1: What made business people join:
The First World War brought them large profits and strength. They were then keen to expand, but colonial rules held them back.
They wanted the government to put a check on foreign imports and to fix the rupee-sterling exchange rate in a way that would not favour imports.
Step 2: Their organisations:
To speak with one voice, they set up the Indian Industrial and Commercial Congress (1920) and FICCI (1927).
Purshottamdas Thakurdas and G. D. Birla were among their leaders. They criticised how the British controlled the Indian economy.
Step 3: How they helped the movement:
At the start of the Civil Disobedience Movement the industrialists backed it. They gave money to the Congress and refused to buy or sell imported goods.
This made the boycott of foreign goods stronger.
Step 4: What swaraj meant to them:
For many businessmen, swaraj meant freedom from restrictions on business, so that trade and industry could flourish.
Step 5: Why the support was not steady:
When the Round Table Conference failed, the mood changed. They feared militant actions and long breaks in business. They were also uneasy about socialist ideas that were gaining ground among young Congress members.
Final Answer:
Business groups supported the movement by funds and boycott because they wanted freedom to grow, but their support became uncertain after the Round Table Conference.
