March 25: holidays and events on this day

March 25 is the Day of the Security Service of Ukraine, the International Day of Remembrance for Victims of Slavery and the Transatlantic Slave Trade, the International Day of the Unborn Child, the International Day of Solidarity with Detained and Missing Employees, and World Mathematics Day. This day combines events that took place in different years. They reflect the struggle for power, scientific discoveries, social changes, and cultural phenomena of different eras.
Day of the Security Service of Ukraine
March 25 is celebrated in Ukraine as a professional holiday for employees of the Security Service of Ukraine. The date was chosen in honor of the adoption in 1992 of the law that defined the legal basis for the activities of this special service of an independent state. The holiday was established in 2001 by presidential decree to honor employees responsible for state security, counterintelligence, the fight against terrorism, and the protection of the country’s sovereignty.
The Security Service of Ukraine performs tasks to prevent threats to national security, counteract espionage, cybercrime and organized crime. In modern war conditions, its role has significantly increased, in particular in exposing sabotage groups, protecting critical infrastructure and the information space. SBU employees work in close cooperation with other security agencies, ensuring the stability of the state.
Interesting facts
The first Ukrainian state security agency after the declaration of independence was created on the basis of the former KGB of the Ukrainian SSR, but a significant part of the personnel had to be replaced due to issues of loyalty to the new state.
There are units within the SBU structure that specialize in cybersecurity, and they participated in the investigation of some of the largest cyberattacks in Europe, including the NotPetya virus, which also affected Ukrainian systems.
The official trident on the SBU emblem has a special shape with a sword, symbolizing the protection of the state, not an attack, reflecting the defensive nature of the service.
In the 1990s, the SBU managed to prevent the illegal export of nuclear materials from the territory of Ukraine after the collapse of the USSR, which was of importance for international security.
Ukrainian special services actively use open sources of information and social media analytics to identify threats, which has become especially important during hybrid warfare.
The SBU has its own educational institutions, where specialists are trained taking into account modern challenges, including information operations and cryptography.
During World War II, various special services of several states operated on the territory of Ukraine, and this experience influenced the formation of modern approaches to security.
Ukraine is among the states that voluntarily abandoned nuclear weapons, and the issues of their protection and control in the 1990s were largely coordinated by the security services.
Over the years, the SBU has exposed high-profile corruption schemes in the public sector, which allowed it to return significant amounts of money to the budget.
International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade
Today, the world commemorates the millions of people who became victims of the transatlantic slave trade. This day was introduced by the United Nations in 2007 to recall one of the largest crimes in human history, when millions of Africans were forcibly transported to America over several centuries. The slave trade was accompanied by cruelty, high mortality during transportation, and complete deprivation of rights.
The transatlantic slave trade lasted from the 15th to the 19th centuries and had a significant impact on the demography, economy, and development of various regions of the world. It contributed to the enrichment of European states and colonies, but led to the destruction of societies in West Africa. The day highlights the importance of preserving historical memory and combating racism and discrimination, the consequences of which are still felt today.
Interesting facts
According to various estimates, more than 12 million Africans were transported across the Atlantic Ocean, but a significant number of people died before they arrived due to inhumane conditions on ships.
The so-called “middle way” between Africa and America lasted several weeks or months, and people were kept in cramped holds without sufficient food, water and air.
In the British Empire, slavery was abolished in 1833, but slave owners received financial compensation from the state, while the freed people themselves received nothing.
One of the first known slave revolts on the ship “Amistad” in 1839 drew international attention to the problem of slavery and became a symbol of the struggle for freedom.
There was no transatlantic slave trade in what is now Ukraine, but Ukrainians themselves fell into slavery during raids, including to the Ottoman Empire, at various historical periods.
Some African rulers participated in the slave trade, selling captives or representatives of other tribes to European traders.
In the United States, slavery was finally outlawed only after the Civil War and the passage of the 13th Amendment to the Constitution in 1865.
In the Atlantic Ocean, there are mass burial sites for people who died during transportation, and they are sometimes called “underwater cemeteries of history.”
In many Caribbean countries, descendants of slaves make up the majority of the population, and their culture has significantly influenced the language, music, and traditions of the region.
International Day of the Unborn Child
This day is dedicated to the protection of life before birth. The date is associated with the Christian tradition of celebrating the Annunciation and is used in a number of countries to emphasize the ethical, medical and social aspects of pregnancy. The initiative was first introduced at the end of the 20th century in Latin America, after which it spread to other countries.
This day is associated with discussions on human rights, reproductive health and state policies in the field of maternity protection. In different countries, the approach to this topic varies significantly: from a complete ban on abortion to its legality under certain conditions. The event is used as an occasion for public discussion of support for pregnant women, the development of medicine and ethical issues that arise around the beginning of human life.
Interesting facts
The first country to officially introduce this day at the state level was El Salvador in 1999, where it has the status of a national commemorative date.
The date of March 25 was chosen because it is symbolic of the nine months before Christmas in the Christian tradition, which is associated with the idea of the beginning of life.
In some Latin American countries, medical consultations and free examinations for pregnant women are organized on this day.
In Ukraine, this day does not have an official state status, but is commemorated by religious and public organizations.
In Poland, there is a practice of spiritual adoption of an unborn child, which lasts nine months and involves daily prayer.
Various international organizations have opposing positions on this day, as it is often associated with debates about women’s rights and access to medical services.
Modern medicine allows recording the heartbeat of the embryo in the early stages of pregnancy, which has become an important argument in public discussions.
In some countries, there are special programs to support pregnant women in difficult life circumstances, which include financial assistance and psychological support.
The first images of a human embryo using ultrasound appeared in the middle of the 20th century, which significantly influenced the scientific understanding of human development before birth.
International Day of Solidarity with Detained and Missing Personnel
This day is dedicated to international organization personnel who have been detained, kidnapped or disappeared in the course of their duties. It was established by the United Nations to draw attention to the dangers faced by humanitarian missions, peacekeepers and civilian personnel in conflict zones. The date is associated with the kidnapping in 1985 of journalist Alec Collett, who worked for one of the UN agencies.
International organization personnel often work in regions with high levels of instability, where there is a risk of violence, terrorism or unlawful detention. This day emphasizes the need to ensure their protection, respect for international law and accountability for crimes against humanitarian personnel. It also recalls the importance of supporting the families of the missing and continuing the search for those whose fate remains unknown.
Interesting facts
Alec Collett, in whose honor the date was chosen, was kidnapped in Lebanon and held captive for several years, and information about his death was confirmed only a decade later.
According to international organizations, every year dozens of humanitarian workers are attacked or kidnapped in different parts of the world.
The most dangerous for UN employees are considered to be regions of active armed conflicts, in particular parts of Africa and the Middle East.
International humanitarian law provides special protection for civilian personnel of humanitarian missions, but in practice these norms are often violated.
In Ukraine, after 2014, the number of cases of illegal detention and disappearance of people in the conflict zone increased, which also attracted the attention of international organizations.
Some humanitarian workers continue to perform their duties even after the abduction of colleagues, which indicates a high level of professional dedication.
There are special UN mechanisms to track missing personnel and coordinate international efforts to find them.
In different countries of the world, families of missing personnel form associations to support each other and draw attention to their stories.
Some abductions of humanitarian workers are used as a tool of political pressure or exchange, making it difficult for them to be released.
World Mathematics Day
This day is dedicated to popularizing mathematics and developing interest in exact sciences among pupils and students. It was launched as a global educational initiative that unites participants from different countries through interactive competitions and online platforms. The main goal is to show mathematics as an accessible and interesting field that plays an important role in the modern world.
This day promotes the development of logical thinking, analytical skills and the ability to solve complex problems. Educational institutions and organizations use it to hold competitions, quizzes and educational events that help overcome the fear of mathematics. Millions of schoolchildren participate in such initiatives, making the event one of the largest educational activities in the world.
