Settlers and rice farmers from Dai Viet, or Annam (present northern Vietnam), have gradually occupied the northern portion of the largely maritime Champa kingdom, protected in so doing by their expansionist government.
The Chams make successful retaliatory incursions into the Red River delta region until forces under Viet ruler Le Dai Hanh occupy and plunder the Cham capital, exacting heavy tribute.
The Viets eventually force the Chams to cede the region of Amaravati (Quang Nam).
Vijaya (Binh Dinh) becomes the Cham capital.
The Second Goryeo-Khitan War is a conflict between the kingdom of Goryeo and Khitan forces near what is now the border between China and North Korea.
The Chinese employ explosive grenades and bombs filled with gunpowder, or black powder, by the beginning of the eleventh century. This mechanical mixture of ten percent sulfur, fifteen percent charcoal, and seventy-five percent saltpeter (potassium nitrate), is generally thought to have originated in China.
The Regulation of Saint Veneration and the Institution of Canonization
As Christianity spread and evolved, the Church sought to regulate the veneration of saints, ensuring a uniform and authoritative process for recognizing those deemed worthy of public devotion. By the High Middle Ages, the institution of canonization emerged as a formalized system, replacing earlier, more localized and spontaneous recognition of saints.
Early Veneration and the Need for Regulation
- In the early centuries of Christianity, martyrs and confessors were venerated spontaneously by local communities, often through oral tradition and local cults.
- Bishops played a role in recognizing saints, but the process remained informal and decentralized, leading to inconsistencies in who was venerated and why.
- As the Church grew, concerns arose over the authenticity of relics, exaggerated miracle accounts, and the potential for superstition, necessitating a structured system of recognition.
The Development of Canonization
To standardize the recognition of saints and reinforce ecclesiastical authority, the Church established a formal canonization process, which included:
- Official criteria for sainthood, ensuring that candidates demonstrated heroic virtue, holiness, and, in many cases, miracles attributed to their intercession.
- A formalized investigation process, where Church authorities verified the life, deeds, and miracles of a prospective saint.
- The papal declaration of sainthood, which became the exclusive right of the pope from the 12th century onward, ensuring uniformity across Christendom.
Integration into the Liturgical Calendar
- Once canonized, most saints were assigned a feast day, aligning their veneration with the liturgical calendar.
- This integration reinforced religious practice, allowing communities across Europe to commemorate saints in a structured manner.
- Saints became patrons of specific places, professions, or causes, further embedding them into medieval spiritual and cultural life.
Impact on Medieval Christendom
- The formalization of saint veneration reinforced Church authority over popular devotion, limiting local and unregulated cults.
- It shaped medieval spirituality, with saints serving as models of Christian virtue and intercessors between the faithful and God.
- The process strengthened papal influence, as the power to declare sainthood was centralized under Rome, demonstrating the Church’s ability to define and regulate holiness.
Legacy
The institution of canonization became a cornerstone of medieval Christianity, defining who was venerated, how, and why. This structured approach helped unify religious practice, reinforcing the Church’s role as the ultimate guardian of faith and devotion in the medieval world.

East Central Europe (1000–1011 CE): Polish Royal Recognition, Foundation of the Hungarian Kingdom, and Imperial Influence under Otto III and Henry II
Between 1000 and 1011 CE, East Central Europe—encompassing present-day Poland, Czechia, Slovakia, Hungary, and the eastern parts of Germany and Austria east of 10°E and north of the previously defined southeastern boundary—experienced pivotal transformations. This era witnessed the formal recognition of Polish sovereignty with Bolesław I’s coronation-like elevation, the foundation and official Christianization of the Kingdom of Hungary under Stephen I, and sustained imperial influence from the late Ottonian emperors, particularly Otto III and Henry II. These critical events fundamentally reshaped the region’s medieval political and cultural landscape.
