What did the conch mean in Lord of the Flies?

it is his "claim to fame" as he found it, and this is the first time i the novel we see how knowledgeable he is. It is also a symbol for peace which he desperately hold on to, even as he dies. the conch shell was used to call all the boys together. In this respect, it is a symol of unity. It was laso held by the person speaking, which was a rule. This makes it a symbol of order and reasonable thinking. When it is destroyed it symbolises the loss of all sensible thinking and the start of total anarchy which is what Piggy feared the most
