A Russian military invasion of eastern Ukraine changed both the political and military landscape.
For a year after the conflict, the conflict and its aftermath seemed like an endless political battle between Moscow and Kiev.
In 2016, however, the war was a diplomatic stalemate and the two countries were united in their opposition to Moscow.
The war that followed in 2017 was one of the most significant conflicts of the 20th century.
As part of the Cold War, the two sides waged a war of attrition against each other, but the war brought new opportunities for economic and political cooperation and, perhaps most importantly, it gave the former Soviet republics their first democratic president since the collapse of the Soviet Union in 1991.
The conflict that began in mid-December 2017 in Ukraine’s Donetsk region is also known as the “DPR” (Donetsk People’s Republic) conflict.
It is considered one of Russia’s most important military engagements, as it helped Russia take over the breakaway region of Crimea and eventually annex the peninsula.
But it also marked a major turning point in the long history of Ukraine’s relationship with Russia.
The country’s political crisis had begun to unravel months before, but it was only when the conflict started in late January that the war started to escalate.
The first sign of trouble came on January 10, when pro-Russian separatists in eastern Ukraine began to fire rockets at Ukrainian military targets.
The following day, a convoy of Russian trucks began to appear in the area around the town of Mariupol, about 30 miles southeast of the rebel-held city.
This convoy, dubbed the “Black Sea Fleet,” was quickly followed by a convoy containing about 200 Ukrainian tanks, artillery pieces, tanks and infantry fighting vehicles.
Russian military officials initially believed that the convoy was headed for the border with Ukraine, but when Ukrainian border guards intercepted the convoy and tried to stop it, they were forced to fire back.
After a brief firefight, the Russian tanks and other vehicles fled the area.
By the next day, the Ukrainian military had been able to hold the Ukrainian side of the border, but they did not have enough weapons to stop the Russian attack.
The Ukrainian army was able to retake Mariupovsk, and the situation calmed down somewhat.
The Russian military was still attacking Ukrainian forces on the eastern side of its border, and they had also started to send armored vehicles and other military equipment to the Ukrainian border, although the Ukrainian army had been holding out in the face of Russian advances.
On February 12, the first Russian military convoy, a transport ship called the “Komodo” entered the Crimean peninsula, and two days later, a second transport ship, the “Artyom” entered Ukraine.
The two ships arrived in Crimea on February 14 and transported Russian military equipment, including armored vehicles, and troops.
Russian officials later claimed that the two ships were part of a Russian military buildup.
The next day on February 15, Ukrainian military forces launched a counterattack on the Russian convoy and captured the first Ukrainian-operated ship, which they then transported to a port in the Black Sea.
On the following day the Ukrainian forces also captured another Ukrainian-operated ship, but Russia claimed that this vessel was carrying a humanitarian aid convoy, the ship that was later sunk by a Ukrainian naval blockade.
The ship was also claimed to have been carrying Russian troops.
However, the capture of the Ukrainian-controlled ship did not immediately bring an end to the war.
After the capture, Ukrainian forces launched an attack on the convoy again.
The convoy was able hold for a little over two weeks, but by the end of the month, the situation was back to normal.
Ukrainian troops had regained some control over their border with Russia, and many were able to return to their homes in Crimea.
But, it was not until April 7, the day the Russians started to invade, that the conflict officially ended.
At the same time, the Kremlin announced that the country had signed a peace deal with Ukraine.
In response to the ceasefire, Ukrainian Prime Minister Arseniy Yatsenyuk announced that Ukraine was withdrawing from the peace deal, but he did not say what that meant in the treaty.
By this time, however (and according to a leaked memo by Ukraine’s intelligence agency) the Kremlin was already prepared to accept Ukraine into the European Union, and it also seemed to be preparing to join NATO.
However the agreement between the two powers had yet to be ratified by all members of the EU.
After Ukrainian forces finally withdrew from the Russian-controlled border on April 11, Russia was ready to start deploying troops on the territory of the new Ukrainian state.
As the Russian military started to push into the Ukrainian territory, Ukrainian officials began to worry that Russia might also try to invade the region.
At this time Russia also began to begin sending humanitarian aid and aid to the people of the Donetsk and Luhansk regions.
Russia’s military presence in eastern and southeastern Ukraine is not new.
After World War II, Russia began its
