Item 1.   Security and Issuer.
------    -------------------

     Item 1 is hereby supplemented as follows:

     The title of the classes of equity securities to which the Statement
relates are the Class A Common Stock, par value $.01 per share (the "Class A
Common Stock"), and the Class B Common Stock, par value $.01 per share (the
"Class B Common Stock"), of Donegal Group Inc. ("DGI").

     On April 19, 2001, DGI amended its Certificate of Incorporation (the
"Amendment") to, among other things:

     o    authorize 30,000,000 shares of a new class of common stock with
          one-tenth of a vote per share designated as Class A Common Stock with
          a par value of $.01 per share;

     o    (a) reclassify DGI's then existing $1.00 par value per share Common
          Stock as Class B Common Stock, par value $.01 per share, (b) effect a
          one-for-three reverse split (the "Reverse Split") of the Class B
          Common Stock and (c) reduce the number of authorized shares of Class B
          Common Stock from 20,000,000 shares to 10,000,000 shares;

     o    establish the rights, powers and terms of the Class A Common Stock and
          the Class B Common Stock; and

     o    retain the authority to issue 2,000,000 shares of Series Preferred
          Stock, par value $.01 per share.


     DGI distributed as a stock dividend (the "Stock Dividend") two shares of
Class A Common Stock to each holder of a share of Class B Common Stock of record
as of the close of business on April 19, 2001.

     As a result of the Reverse Split and the Stock Dividend, each stockholder
of record as of the close of business on April 19, 2001 continued to own, except
for any fractional interests, which were paid in cash, the same number of DGI
shares, two-thirds of which were shares of Class A Common Stock and one-third of
which were shares of Class B Common Stock, and each such holder continued to
have the same percentage ownership in DGI. Based upon the number of shares
outstanding following the Reverse Split and the Stock Dividend, the holders of
Class A Common Stock are currently entitled to an aggregate of 596,266 votes, or
approximately 16.70% of the total votes at any meeting of stockholders and the
holders of Class B Common Stock are currently entitled to an aggregate of
2,973,245 votes, or approximately 83.30% of the total votes, at any meeting of
stockholders.

Item 3.  Source and Amount of Funds or Other Consideration.
------   -------------------------------------------------

     Item 3 is hereby supplemented as follows:

     On February 15, 2000, May 15, 2000, August 15, 2000 and November 15, 2000,
pursuant to the Donegal Group Inc. Dividend Reinvestment and Stock Purchase Plan
(the "Dividend Reinvestment Plan"), Donegal Mutual Insurance Company (the
"Mutual Company") purchased 73,251 shares, 61,463 shares, 67,984 shares and
51,014 shares, respectively, of Common Stock at prices of $6.26 per share, $7.56
per share, $6.92 per share and $9.32 per share, respectively, representing the
average of the closing prices per share of Common Stock on the Nasdaq National
Market for the five trading days preceding the applicable dividend payment date,
as determined in accordance with the terms of the Dividend Reinvestment Plan,
for a cost of $458,255, $464,847, $470,379 and $476,497, respectively.

     On February 15, 2001, pursuant to the Dividend Reinvestment Plan, the
Mutual Company purchased 45,140 shares of Common Stock at a price of $10.65 per
share, representing the average of the closing prices per share of Common Stock
on the Nasdaq National Market for the five trading days preceding February 15,
2001, as determined in accordance with the terms of the Dividend Reinvestment
Plan, for a cost of $481,097.

     Effective April 30, 2001, DGI amended the Dividend Reinvestment Plan to
provide that only Class A Common Stock would thereafter be purchasable with
reinvested dividends and voluntary cash payments.

     On May 30, 2001, pursuant to the Dividend Reinvestment Plan, as amended,
the Mutual Company purchased 39,951 shares of Class A Common Stock at a price of
$13.44 per share, representing the average of the closing prices per share of
Class A Common Stock on the Nasdaq National Market for the five trading days
preceding May 30, 2001, as determined in accordance with the terms of the
Dividend Reinvestment Plan, for a cost of $537,106.
