Chai, or tea, has evolved from ancient medicinal brews to a daily ritual in India, symbolizing unity and community. The origins of chai can be traced back to ancient India, where it was made with a mixture of spices and herbs known as "masala". This mixture was believed to have medicinal properties and was used to treat a variety of ailments. Over time, the recipe for chai evolved to include tea leaves and milk, and it became a popular drink in India and other parts of South Asia. 

The British East India Company began large-scale production of tea in Assam in the early 1820s, establishing tea gardens and promoting tea consumption. However, it wasn't until the early 20th century that tea became widely popular domestically. The Indian Tea Association played a significant role in promoting tea consumption by encouraging factories, mines, and textile mills to provide tea breaks for their workers. 

Today, chai is an integral part of Indian culture, served in homes, offices, and roadside stalls, uniting people across regions and communities. Its rich history and cultural significance continue to make it a beloved beverage in India.
