Accounting has existed for thousands of years, with evidence of accounting practices found in ancient Babylon from 2600 BC. However, modern accounting using double-entry bookkeeping was established in the 15th century by Fra Luka Paciolo. Accounting was also practiced in ancient India as described in Kautilya's Arthashastra, but modern accounting was introduced after 1850 with the formation of joint stock companies. Accounting involves systematically recording all financial transactions and preparing reports and interpreting the information to analyze a business's performance and financial position.
