The Hasinai confederation (Hasí:nay in Caddo) was a large confederation of Caddo-speaking Native Americans located between the Sabine and Trinity rivers. They were known as the Tejas by Spanish explorers, being the plural Spanish version of the Caddo word táysha, "friend". This name was later given to the state of Texas. They are also referred to as Hasini, Asenai, Assoni, Asenay, Cenis, Asinai.
