the history behind
the Windrush Poles
The history of how the Windrush Poles came to be on the ship in 1948 began around a decade earlier, in what was then eastern Poland.

In the impending shadow of WW2, Germany under Adolf Hitler and the Soviet Union under Joseph Stalin signed a secret pact in which they agreed that they would not attack each other and that they would carve up Poland between them. This was the Molotov-Ribbentrop Pact, signed on 23 August 1939.
On 1 September 1939, Hitler invaded Poland from the west, and on 17 September 1939 the Soviet Union invaded Poland from the east. They met at what was known as the Curzon Line, a boundary that had first been proposed during the Polish–Soviet War of 1919–20.
After the invasion, Poland had effectively ceased to exist as a separate country. The reality for the Poles living in the east of what was formerly Poland, was that they were now on land controlled by Russian forces.

The western part of Poland had been taken over by Germany and so the Polish Government now had no safe place from which to govern. Its members fled to France and subsequently to England, becoming a government-in-exile.
Stalin conducted mass deportations of Polish nationals to the Soviet Union, including Kazakhstan and Siberia, in February, April and June 1940 and June 1941.
Approximately 1.5 million Poles were taken in this way. They were placed in unheated cattle trucks with no food and sent over 1,000 miles to forced labour camps. There they had to live in primitive conditions and do hard manual work in exchange for basic subsistence. For those in Siberia the temperatures were sub zero for months of the year, and could plummet below -20°C in winter. 
However, this situation was to change. On 22 June 1941 Germany invaded the Soviet Union in Operation Barbarossa. Hitler was no longer honouring the Molotov-Ribbentrop Pact; he had become Stalin’s enemy. German forces swept eastwards, taking over the Polish territory that the Soviet Union had acquired under the pact.
General Władysław Sikorski, Commander-in-Chief of the Polish Army and Prime Minister of the Polish Government-in-Exile, took advantage of the situation to persuade Stalin to release the Poles from the labour camps. He proposed that the Poles would be able to assist Stalin in fighting the Nazis.
Reluctantly, Stalin agreed to what he called an ‘amnesty’ for the Poles in the labour camps, on condition that they would join a newly formed army led by Polish General Władysław Anders. They had to make their way to Uzbekistan though, from where most were taken to Iran.
Stalin did nothing to help the departing refugees, and in many cases, they were hindered from leaving. Those Poles who did manage to go had to make their own way across several thousand miles. So brutal had their living conditions been and so difficult was the journey they now had to make, that many Poles died of exhaustion and malnutrition. Fewer than 10 per cent of those who had been taken from their homes in Poland successfully made that journey from Soviet Russia.
US President Franklin D. Roosevelt, British Prime Minister Winston Churchill and Soviet Premier Joseph Stalin met at three conferences held during and after the war, at which they discussed the boundaries of Poland. These were the Tehran, Yalta and Potsdam Conferences. The outcome of these was that the Soviet Union would retain land to the east of Poland. 
This meant for many Poles like Janina, that they could not return home, as they would be under the occupying communist regime, unlikely to regain their lost land and in danger of persecution.
From Iran, the civilians who had escaped from the labour camps were dispersed to countries that had indicated a willingness to take them. These included Mexico, New Zealand, Lebanon and British colonies in Africa and India. The Folta women ended up at Santa Rosa, an old hacienda near León in Mexico.
The Poles who had fought for the Polish Free Forces, supporting the Allies, were eventually given the right to bring their relatives to England under the Polish Resettlement Act 1947. Those who took this up were initially settled in camps, later gradually integrating into British society. Those who did not found permanent homes in other countries.
In May 2017 the Polish Government estimated that there were 18–20 million  Poles now living outside the borders of their own country. This Polish diaspora is one of the biggest in the world.
