Explanation:

Introduction:
The Ahmedabad Satyagraha was a significant movement led by Mahatma Gandhi in India during the early 20th century. Satyagraha means "truth force" or "holding onto truth". It was a nonviolent resistance movement aimed at achieving political and social change. The movement primarily targeted mill owners in Ahmedabad, a city in the state of Gujarat, India.

Background:
During the colonial era, India was under British rule, and the textile industry played a crucial role in the country's economy. Ahmedabad was a major center for textile mills, which employed a large number of workers, mostly from the lower socio-economic strata. These workers faced various issues related to working conditions, low wages, and long working hours.

Reasons for targeting mill owners:
1. Low wages and poor working conditions: The mill workers in Ahmedabad were subjected to exploitative conditions, with low wages and long working hours. Gandhi believed that the mill owners were responsible for these injustices and sought to address these issues.
2. Social inequality: Gandhi's philosophy of nonviolence and equality aimed to challenge the existing social order. He believed that the mill owners represented the oppressive capitalist system and needed to be confronted in order to bring about social change.
3. Labor rights: Gandhi advocated for the rights of the workers, including fair wages, better working conditions, and the right to organize and form labor unions. By targeting mill owners, he aimed to raise awareness about the plight of the workers and fight for their rights.
4. Economic exploitation: The mill owners were seen as profiting from the labor of the workers while paying them meager wages. Gandhi sought to challenge this economic exploitation and create a more equitable society.

Conclusion:
The Ahmedabad Satyagraha led by Gandhi was directed against mill owners in Ahmedabad. It aimed to address the issues faced by the workers in the textile mills and fight for their rights and better working conditions. Gandhi's movement played a significant role in raising awareness about labor rights and challenging the oppressive capitalist system prevailing during that time.
