Azzawi graduated in archaeology from the Baghdad University in 1962, and in fine arts from the Institute of Fine Arts, Baghdad in 1964. In 1969 he formed the art group 'New Vision' with some of his contemporaries; among them Rafa al- Nasiri, Mohammed Muhriddin, Ismail Fattah, Hachem al-Samarchi and Saleh al-Jumaie. He later joined the 'One Dimension' group started by Shakir Hassan al-Said but remained close to 'New Visions' until 1972.He has exhibited extensively in the Middle East, North Africa, the US, India, Brazil and Europe, including a retrospective exhibition ‘Dia Azzawi’ at the Institute of the Arab World, Paris in 2002. He has received several awards, among them first prizes at the International Summer Academy, Salzburg, Austria in 1975 and at the First Arab Contemporary Art Exhibition, Tunis in 1981. He also won the Jury Prize at the International Cairo Biennial in 1992. Azzawi moved to London in 1976 where he worked as an art consultant at the Iraqi Cultural Centre between 1977 and 1980.
A prominent artist of the Iraq school, Azzawi also plays an important role in the promotion of Iraqi and Arab art to wider audiences through numerous exhibitions of his contemporaries work and in authoring publications. Azzawi has been an exile from his Iraq for over thirty years and he currently lives and works in London.
Azzawi's work includes paintings, sculptures, prints, drawings as well as books in which visual art interacts with prose and poetry. A number of critics have acknowledged how Azzawi’s artwork has escaped the attribution of a particular cultural style. Despite the Arabic and Western influences in his life, his art is non-reducible in this way. His painting can be said to be loosely based on pre-Islamic styles but are not preoccupied by this. His art intends to cross geographical and cultural boundaries, providing an aesthetic that is potentially universal. Azzawi’s work intends to be joyous in dealing with life in all its aspects. His cross-cultural approach intends to forge an Arab identity that can be understood and linked to the west instead of highlighting the differences.
Azzawi’s artwork always appears in bright vibrant colours frequently featuring abstract figures or symbols from legendary Sumerian periods, which create an ambiguity and mystery within the storytelling. Shapes often fuse with shadows or indistinguishable forms creating an inner motion. Set in the nostalgia of the past his paintings also defy inevitability and reach into the future and to freedom.
