Otto I: Life, Reign, and Legacy of the Holy Roman Emperor
Otto I was born on November 23, 912, as the oldest son of Henry the Fowler.

The first two months of 2019 were marked by significant geopolitical transitions, advancements in space exploration, and notable shifts in international policy. From the inauguration of new leadership in Brazil to the historic landing of the Chang'e 4 probe on the far side of the Moon, the period set a complex tone for the remainder of the year.
January 2019 saw several major changes in national leadership and international alliances. Jair Bolsonaro assumed the presidency of Brazil, beginning a four-year term. Simultaneously, Romania took over the Presidency of the Council of the European Union, succeeding Austria. In the Middle East, Qatar officially withdrew from OPEC, signaling a shift in regional energy policy. The political landscape in Venezuela became increasingly volatile, leading to a presidential crisis as the National Assembly challenged the legitimacy of Nicolás Maduro.
Space exploration achieved a historic milestone on January 3, 2019, when the Chinese Chang'e 4 probe became the first artificial object to land on the far side of the Moon. Earlier in the month, the New Horizons spacecraft completed its close approach to the Kuiper belt object 486958 Arrokoth, providing unprecedented data on the outer reaches of the solar system. In February, the private sector made strides with the launch of the Beresheet probe by SpaceIL, representing the first privately financed lunar mission.
The beginning of 2019 brought significant updates to intellectual property law. Works published by authors who died in 1948 entered the public domain in many jurisdictions. Notably, in the United States, works published in 1923 entered the public domain, marking the first such expansion of the public domain since 1998. Meanwhile, in the corporate sector, the Adventist Health System underwent a major rebranding, adopting the trade name AdventHealth.
The period was also characterized by heightened international tensions. The U.S. Justice Department's charges against Huawei in late January exacerbated trade frictions between the United States and China. In February, the United States and Russia both suspended their obligations to the 1987 Intermediate-Range Nuclear Forces Treaty. Additionally, the Indian Air Force conducted airstrikes in Balakot, Pakistan, triggering a significant standoff between the two nuclear-armed nations.
It marked the first time since 1998 that published works entered the public domain in the United States, following the expiration of extended copyright terms.
