Geographical location of Crimea:
At the southern tip of Ukraine, stands a shining pearl - the Crimean peninsula. This jewel in the northern part of the Black Sea is like an eagle soaring with its wings, stretching its talons on the Kechi Peninsula and pointing straight into the boundless sea. To the northeast is the smaller Sea of Azov, which resembles an emerald inlay in the land of Crimea.
In the vast river of history, the Crimean Peninsula is like a bright pearl, carrying vicissitudes and glories. Its name is derived from the Tatar word "Crimea", the honorific name of the early Tatar khans, as if to tell the ancient and mysterious story of this land. The ancient Greeks called it Tauris, another beautiful name that also revealed the place of Crimea in ancient civilization.
The Crimean Peninsula, also translated as the Crimean Peninsula, covers an area of 25,500 square kilometers and has a population of about 2.5 million, making it the largest peninsula in Europe. This rich land was ruled by the Goths in 250, the Xiongnu in 376, the Khazars in the 8th century, the Byzantine in 1016, and the Mongol Golden Horde in 1237. At that time, Russians also lived on this land and suffered from the oppression of foreign forces.
Despite its name as a peninsula, Crimea's northern border with Ukraine is as narrow as a sky, making it more of an isolated island. It is as large as the two municipalities of Beijing and Tianjin combined, and far more than many small European countries. Despite being sparsely populated compared to China's vast lands, Crimea is a densely populated region for Europe.
It's a picturesque place with a rich history, and ancient legends tell in every corner. Crimea, a unique place of natural beauty, history, culture and abundant resources, is waiting for the world to explore and discover.
History of Crimea:
It was not until 1502, when the Golden Horde collapsed, that Russia and Crimea gained real independence. Then, Russia gradually rose, and in 1783, the entire Crimean peninsula was officially incorporated into Russian territory. This marked the beginning of Russia's sovereignty over Crimea, which has only been around for more than 300 years. However, this land is inhabited not by Russians, but by Tatars.
During World War II, the Tatars collaborated with the German army and aspired to create their own state, but were eventually liquidated by Stalin. Many Tatars on the Crimean peninsula were exiled, and about 46% died of starvation or disease. This history is painful and reminds us to appreciate the importance of peace and stability even more. The question of the belonging of Crimea:
Historically, Crimea was part of the Soviet Union, and after the collapse of the Soviet Union, Crimea was part of Ukraine. However, the situation on the Crimean peninsula has been in turmoil since 2014. After a series of political and military games, Crimea's declaration of independence and subsequent accession to the Russian Federation has caused widespread concern and controversy in the international community.
In the midst of history, the question of the ownership of Crimea has always been a game between Russia and Ukraine. Tracing the long history,The establishment of the Crimean Khanate in 1949, which was subordinate to the then Mongolian Golden Horde, is like a bright pearl inlaid in the crown of history. However, in 1783, Crimea was annexed to Tsarist Russia, and a new journey began. In 1921, the Crimean Autonomous Socialist Republic was established, which seemed to herald the beginning of a new history.
However, the chapters of history are not always straightforward. During the Soviet era, Crimea was annexed to Ukraine in 1954, a decision that laid the groundwork for the subsequent ownership dispute. After the collapse of the Soviet Union, Crimea became the only autonomous republic of Ukraine through a referendum, and at the same time, the main base of Russia's Black Sea Fleet was stationed in the Crimean port city of Sevastopol, which further complicated the question of Crimea's ownership. 
Fast forward to 2014, and the history of Crimea ushered in an important turning point. That year, Crimea held a referendum on whether to reunite with Russia. On March 16, the results of the referendum were announced, with about 97% of the votes cast in favor of joining Russia. This result is like a bombshell, which has aroused widespread concern in the international community. On the 17th, Putin signed the "Decree on the Recognition of the Republic of Crimea", recognizing the Republic of Crimea (including the city of Sevastopol) as a sovereign and independent state. On the 18th, the Prime Minister, the Speaker of the Parliament and the Mayor of Sevastopol of the Republic of Crimea signed a treaty with Russia, and the Republic of Crimea (including the city of Sevastopol) officially joined the Russian Federation, and a new federal subject was born. 
This historic change is like a magnificent picture, depicting the inextricable links and complex historical entanglements between Crimea and Russia and Ukraine. Today, Crimea is part of RussiaThis history will continue to write a new chapter.
From the perspective of international law, a country's territorial sovereignty is usually based on factors such as its history, culture, and ethnicity. Ukraine, as an independent sovereign state, has the legitimacy of its territorial integrity. Russia's claim to Crimea is based on its historical control and influence over the region. Therefore, the settlement of the Crimean issue needs to take into account a number of factors such as international law, geopolitics, ethnicity and history.
Conclusion:
In resolving the Crimea issue, the international community should adhere to the principles of peace, justice and reasonableness, respect the sovereignty and territorial integrity of all countries, and oppose any form of force or coercion. At the same time, the parties should resolve their differences through peaceful means such as dialogue and negotiation and seek a long-term solution to the Crimean issue.
To sum up, the Crimean issue is complex and sensitive, requiring calmness, rationality and restraint on all sides. The international community should make joint efforts to promote a peaceful settlement of the Crimea issue in order to maintain regional peace and stability.
