First off, your paragraphs are not fully developed. To be so, each internal (body) paragraph should have somewhere between 6-8 sentences, giving details to support the topic sentence and your interpretation of those details.
Second, in your first sentence, do you really mean, "...advancements in technology led to a British society that was more geared towards manufacturing than agriculture." It reads as if British society had been based on manufacturing first and was changing to agriculture. This sentence needs to be rephrased so your meaning is clear.
