The ancient empire credited with developing the zero concept in mathematics is the Gupta Empire in India. During the Gupta period, which lasted from approximately 320 to 550 CE, Indian mathematicians made significant advancements, including the formalization of the concept of zero as a number. This development was revolutionary, as it allowed for more sophisticated arithmetic and calculations. The introduction of zero facilitated the evolution of the decimal numeral system and influenced mathematical practices worldwide. The contributions of Indian mathematicians during this era laid the groundwork for future mathematical concepts and are crucial to the history of mathematics.
