Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Condense this historic overview into one sentence: The Roman Empire, founded in 27 BC by Augustus, was the post-Republican period of ancient Rome, characterized by an autocratic form of government and large territorial holdings around the Mediterranean. The Empire's military might, architectural achievements, and cultural contributions shaped Western civilization. It eventually declined due to internal strife, economic troubles, and invasions, formally ending in AD 476 when Romulus Augustulus was deposed.
