The present study is based on propaganda posters of British Empire and its affiliated Australia and New Zealand army corps in the Gallipoli Campaign. The First World War was the first period in which propaganda had become worldly and developing until that time, became institutionalized at the national level and effective at the global level. It is also the only World War in history where posters were used as the main propaganda tool. Later, media such as cinema and radio came to the fore. Over a hundred years ago, Australian and New Zealand soldiers (Anzacs) were sent to Gallipoli. In this study, it was tried to understand what kind of message design was used to bring them from the other side of the world, which visual and textual expressions were used and which propaganda technique was used in the language. Semiology as a qualitative method and propaganda techniques related to language were used for this purpose. The British Empire was a multi-fragmented political system that also included Australia and New Zealand and was the world's (then) biggest political power. Focusing on the war posters about the Battle of Gallipoli also helped to understand the empire's propaganda system. To understand this structure, in addition to the aforementioned methods, the historical background of the development of propaganda and Britain- Australia-New Zealand relations was given. It was observed that the posters of the countries (Australia, New Zealand) connected with the center of the empire were in a meaning chain. There were signs that Britain was conducting a holistic propaganda. Over time the propaganda lost its enthusiasm. After the war ended, it was observed that the intense emotionality and pride of the first poster were again used in the last poster with a different theme. In the last poster (in the context of the Gallipoli Campaign) it was seen that the "British" identity was highlighted. When the posters are examined, it is seen that there is a systematicity in the message flows. As the posters and messages were examined as source and content, it was seen that Britain had a comprehensive propaganda system.
