Between 1,000 and 1,200 people were surveyed online in the UK, as well as in Egypt, France, Germany, India, Russia, and Turkey about their First World War knowledge.
The poll conducted by YouGov for the British Council found:
In the UK fewer than half of the 1,081 people questioned were aware that North America and the Middle East played a part in the First World War, while less than a quarter realised that Africa and Asia were involved.
The research found a widespread lack of understanding about the impact of the war - while 62% of people in the UK were aware of its connection to the rise of the Nazis in Germany, far fewer (37%) were aware of the link with the rise of Communism in Russia.
Less than a third of UK respondents associated the war with the fall of the Ottoman Empire (32%) or the creation of the United Nations (27%), and just 11% were aware of its connection with the ongoing conflict between Israel and the Palestinians.
Across the seven countries, almost three-quarters of people surveyed (72%) believed that their country was still affected by the consequences of the war, the research found.
There were a total of 7,488 responses to the poll - 1,052 in Egypt; 1,029 in France; 1,070 in Germany; 1,215 in India; 1,019 in Russia; 1,022 in Turkey and 1,081 in the UK.
Fewer than half of people in the UK realise the First World War extended beyond Europe, a new report has shown.
According to the report, produced from research by the British Council, most people's knowledge of the Great War - which began 100 years ago - is limited to fighting on the Western Front.
The document - Remember The World As Well As The War - reveals a lack of understanding of the global scale and impact of the war, and calls on the UK and the rest of the world to use forthcoming centenary commemorations to help people gain a better understanding of the global nature of the conflict.
Conservative minister Helen Grant reportedly wrote in The Lady that the First World War victory centenary will not involve "celebrating" nor the "sounding triumphant fanfares".
– Conservative minister Helen Grant as reported in The Lady
We won't be shying away from the fact that, in the end, it was an absolutely vital victory for us that changed the course of world history in countless ways, but we won't be celebrating that fact or sounding triumphant fanfares.
Don't forget that, as well as changing history, the conflict claimed the lives of around sixteen million people across the world, and injured a further twenty million.
The tone has to be right, not four years of gloom and misery, but no dancing in the street either.
Her remarks were also reported in the Times (£).
Britain's First World War victory should not be celebrated with "dancing in the street", the Conservative minister in charge of marking the centenary has said.
Helen Grant said although the war was an "absolute vital victory" for Britain there should be no "triumphant fanfares" throughout the next four years of commemorations. Her comments add to the controversy over how the four-year conflict should be remembered 100 years on.
