Final Answer:
Umbridge secured a teaching position at Hogwarts through Educational Decree No. 23, demonstrating the Ministry's interference in school affairs. This decree allowed the Ministry to appoint teachers directly, setting the stage for Umbridge's oppressive role in the series.
B) Educational Decree No. 23
Step-by-step explanation:
In the "Harry Potter" series, Educational Decree No. 23 is the decree that gave Dolores Umbridge a teaching spot at Hogwarts. This decree empowered the Ministry of Magic to appoint individuals as teachers at the school, bypassing the usual selection process. Umbridge, a character known for her strict and oppressive methods, was installed as the Defense Against the Dark Arts professor through this decree.
Educational Decree No. 23 was a tool used by the Ministry to exert control over Hogwarts during a period of political upheaval in the wizarding world. The decree reflects the interference of the Ministry in the affairs of the school, undermining its autonomy and traditional practices. Umbridge's appointment, enabled by this decree, plays a significant role in the narrative as she becomes a central antagonist, creating tension and conflict within Hogwarts.
This plot point emphasizes the broader theme in the series about the struggle for power and control, with the Ministry attempting to manipulate education for its own agenda. The use of Educational Decree No. 23 serves as a symbol of the growing authoritarianism within the wizarding government and sets the stage for the challenges that Harry and his friends face as they resist this intrusion into their magical education.
